Amid growing concerns about the textile industry’s environmental impact, there is pressure to find greener clothes for your wardrobe, from work blazers to swimsuits. Unfortunately, fashion greenwashing makes it harder for you and all other consumers to figure out which clothing brands offer the most eco-friendly garments. So, we had to ask: Which are the most sustainable activewear brands?

The most sustainable activewear brands are Patagonia, Girlfriend Collective, Tripulse, and Finisterre, which prioritize recycled materials that are low-impact and high-performing while striving for circularity. In addition, Wolven and VAUDE reduce carbon emissions and textile waste. 

Whether you are searching for some perfectly fitting bike shorts or a supportive exercise bra to add to your wardrobe without negatively impacting the soil, the water, the animals, and other people, there is a brand for you. So, let’s keep reading to learn more about the most sustainable activewear brands and how they ensure sustainable, ethical practices. 

Here’s How We Selected the Most Sustainable Activewear Brands

The fast fashion industry has pushed for trendy activewear that requires frequent replacement. Yet, the environmental impacts of making and landfilling clothes can be enormous, especially with certain materials. 

“Sustainable: The ability to be maintained at a certain rate or level | Avoidance of the depletion of natural resources in order to maintain an ecological balance”

Oxford Dictionary

The brands on this list were chosen based on their commitment and actions to promote sustainable practices while reducing the environmental impacts of the textile industry. 

They are transparent about their materials, processes, and workforce management within their supply chain. 

Some brands focus their efforts on reducing waste and optimizing natural resources while others strive to reduce the carbon footprint of their clothes. 

All of these brands share the commitment to reshape the textile industry toward a more sustainable and Earth-friendly sector.

Patagonia: Everyday Wear for Those Who Care

Patagonia was founded in California in 1973 by Yvon Chouinard as a small climbing equipment company committed to environmental responsibility and outdoor adventure. Today, they are a global leader in sustainable outdoor apparel, crafting high-quality, eco-friendly products and calling for change in the “business as usual“ way to tackle the climate crisis and protect the planet. Patagonia makes activewear for trail running, climbing, mountain biking, surfing, skiing, and snowboarding.

“Together, we can prioritize purpose over profit and protect this wondrous planet, our only home.”

Patagonia

Patagonia puts sustainability at the center of their operation. They work to reduce, rather than simply offset, carbon emissions where it matters the most: in the supply chain and material manufacturing. They reduce their carbon footprint by removing high-impact virgin fossil-based fibers from their collections, using “Environmental Profit and Loss” to guide their production decision, and helping their suppliers to cut emissions. Patagonia’s fall 2023 collections are made up mostly of preferred materials (91% by fabric weight), including Regenerative Organic Certified fibers, hemp, man-made cellulose fibers, recycled cotton, and recycled polyester. On top of that, Patagonia’s Worn Wear Program encourages customers to repair and recycle their products, extending the textile lifecycle and reducing waste. Lastly, Patagonia is certified as a B Corporation and a Bluesign^® brand. 

Patagonia commits to fair trade practices. Through the partnership with Fair Trade USA, they currently produce 86% of their clothes in 20 Fair Trade Certified™ factories. Patagonia pays a premium for every item produced in such factories, accumulating in a fund for workers to use in their chosen community projects, whether in healthcare or parent support or to withdraw as a cash bonus. Additionally, they have various social responsibility programs to prevent harm and create positive impacts on the lives of apparel workers in their supply chain. These include the Fair Labor Association, the Living Wage Program, the Migrant Workers Program, and the Responsible Purchasing Practices. Patagonia is also fully transparent about the locations of their facilities and suppliers. 

Since 1985, Patagonia has pledged 1% of sales annually to environmental causes. They have awarded over $89 million in cash and kind donations to domestic and international grassroots environmental groups, making a difference in their local communities. In 2022, the founder of Patagonia gave away his family’s ownership of the company to the newly created Patagonia Purpose Trust and the not-for-profit organization Holdfast Collective, ensuring that all future profits from the company are used to fight the climate and extinction crisis.

Girlfriend Collective: Essential and Timeless Activewear Made Out of Recycled Materials

Girlfriend Collective was founded in Seattle in 2016 by husband-and-wife duo Quang and Ellie Dinh to create eco-conscious activewear that combines sustainability with style and inclusivity. Today, they are a prominent player in sustainable athletic wear, known for their eco-friendly materials and recycling practices. Girlfriend Collective’s activewear is available in an inclusive range of sizes (2XS–6XL) 

“We make everything locally in small batches to make sure we don’t have a negative impact on the environment.”

Girlfriend Collective 

Girlfriend Collective’s sustainability efforts start with using recycled and recyclable textile and packing materials. Their clothes are made from recycled materials such as post-consumer water bottles, fishing nets retrieved from the seas, fabric scraps, and other waste. On top of that, their packaging is 100% recycled and recyclable. After their clothes are dyed, all the wastewater is sent to a treatment plant 100 feet away. Treated water that meets safety standards is released into the waterway, while mud dye is donated to a pavement facility to be turned into paving stones. Additionally, they help prevent microfiber release with a branded microfiber filter. Their program “Recycle. Reuse. Regirlfriend.” collects old Girlfriend Collective compressive leggings and upcycles them into new pieces that can be worn again and again, reducing waste while moving toward a more circular fashion model. Lastly, Girlfriend Collective partners with EcoCart to provide a carbon-neutral option for all orders placed on their site to offset the carbon footprint of their products.

Girlfriend Collective’s facilities are fully certified by Social Accountability International – SA8000. An SA8000 certification guarantees safe working conditions, the right to unionize, and no forced or child labor. They also ensure all workers in their supply chain are paid fair wages and provided with free lunches and guided exercise breaks. 

Girlfriend Collective is not known to be part of any giving-back programs.

Finisterre was founded in Cornwall, England, in 2003 by Tom Kay to provide functional and sustainable activewear, inspiring a love of enjoying and protecting the sea together. Today, they are a recognized leader in sustainable activewear, celebrated for their commitment to transparency, eco-conscious materials, and ethical manufacturing. 

“Yet from our cliff top workshop, we stay true to our original design ethos of functionality and sustainability, remaining committed to product, environment and people.”

Tom Kay, Founder of Finisterre

Finisterre places circular sourcing at the center of their sustainability commitment. They use renewable and recyclable textiles and biodegradable natural fibers and finishes. At least 50% of their clothes are made using recycled fabrics. For example, in 2022, 87% of the synthetic polymer fabrics used in Finisterre clothes were made using recycled fabrics, including polyester recovered from post-consumer and post-industrial waste. They also use low-impact natural fibers, including GOTS-certified organic cotton, hemp, linen, and bamboo. In 2019, they replaced all plastic packaging with water-soluble, ocean-safe, and biodegradable “Leave No Trace” garment bags. Finisterre strives to reduce textile waste by offering repair services and giving in-store credits for gear trades-in, which would be reconditioned for resale. They also implement various incentives to reduce their carbon footprint, including switching more of their stores and offices to renewable energy tariffs and transporting products using less carbon-intensive modes on land and sea. Last but not least, Finisterre is a B Corporation. 

Finisterre is committed to full transparency in their supply chain, holding their partners to the high standards in their Code of Conduct and their Anti-Slavery & Trafficking Policy. Additionally, they partner with Fair Working Conditions (FWC), enabling the mapping of their supply chain, the screening of suppliers, and targeted audits at high-risk locations. Their facilities are also listed on Open Supply Hub. Lastly, Finisterre’s ethical values extend to their dedication to saving the sea. For example, they provide a free resource to inspire ocean activism. 

Finisterre provides financial support to various giving-back campaigns and programs through the Finisterre Foundation, championing ocean access for all. For example, Finisterre turned 2021’s Black Friday into Blue Friday, where they swapped discounts for donations, raising funds for The Wetsuit Project, which adapts wetsuits for children and adults with various disabilities to access the sea. In 2022, Blue Friday was used again to raise money supporting Level Water to provide specialist swimming lessons for children with disabilities. Other projects include The Seasuit Project, City Kids Surfing, Seasuit Donation, and Art Auctioning for Good.

Wolven: Multifunctional Activewear Made From Recycled Bottles 

Wolven was founded in California in 2015 by Kiran Jade and Amanda Lapham to make clothes based on three core principles: sustainability, disruptive design, and community. Today, Wolven is a prominent sustainable fashion brand offering reversible and multifunctional activewear made from recycled plastic bottles.

“Sustainability to us means every decision we make is rooted in our intention to protect our planet and create a more equitable and Earth-centered future for all.”

Amanda Lapham, Co-founder of Wolven 

Wolven ensures their sustainability by sourcing a high proportion of low-impact fabrics. Specifically, all of their 2022 swimwear and activewear was made with 84% recycled polyester fabrics reclaimed from discarded plastic water bottles. Their recycled fabrics are certified with the Global Recycled Standard and OEKO-TEX® STANDARD 100. Additionally, they design their clothes to be reversible and multifunctional so consumers can do more and buy less. Regarding their climate impact, Wolven is certified Climate Neutral for reducing and offsetting their carbon emissions. They also reduce their impact by using emission-free renewable energy in the supply chain and at their office, opting for sea freight shipping over air freight, and recycling packaging materials to reduce waste. Regarding the necessary emissions, they compensate by investing in projects in wind energy and reforestation. Lastly, they further their commitment to circular fashion beyond using recycled material with their resale program, Wolven Pre-Loved. 

Wolven only traces part of their supply chain. Their manufacturing partner is based in China and assessed by Intertek as conforming to the requirements of the Workplace Conditions Assessment. 

Wolven gives back 1% of their annual revenue to nonprofit organizations. For example, each purchase from their Neutral Collection gives back to Climate Neutral through their 1% for the Planet membership. They also partner with CleanHub to organize events to pick up plastic bottles and clean up places like beaches, rivers, and canals.

VAUDE: Outdoor Gear and Activewear Where Performance Meets Ecology

VAUDE was founded in the Alps in Germany in 1974 by Albrecht von Dewitz, inspired by his passion and enthusiasm for mountain sports. Today, VAUDE has earned recognition as a prominent advocate for sustainable active clothing and outdoor gear, widely known for their eco-friendly materials and transparent supply chains. 

“We design with a focus on minimal material consumption, try to avoid waste and design products that are timeless, durable and repairable.”

VAUDE

VAUDE prioritizes sustainability by creating a counterbalance to resource-consuming lifestyles. They achieve that by making durable and versatile products for life, minimizing waste during manufacturing, and enabling longer product lifespan with maintaining, repairing, donating, and upcycling guidance. VAUDE opts for materials that combine technical performance and ecological responsibility. An example of this is their use of merino wool, a natural fiber suitable for a warm and water-repellent protective layer that is ideal for mountain sports. Meanwhile, they lower the impact of this fabric by adhering to the Responsible Wool Standard and the Global Organic Textile Standard for virgin organic wool and increasing the content of GRS-certified recycled wool in their collection. Furthermore, their products have been certified by Bluesign^® and Green Button. Regarding their impact, the brand sets science-based climate goals to reduce global emissions as quickly as possible, aligning with the Paris Agreement’s 1.5 degrees in global warming, and is on track with their target as of October 2022, according to Science Based Targets (SBTi). They achieved that by measuring the total carbon footprint and implementing reduction measures in hotspots like material, energy, and transport. Since the beginning of 2022, VAUDE has been a carbon-neutral company, achieved through fully offsetting their global greenhouse gas emissions in the My Climate’s climate change mitigation project in Vietnam, their most important country of production. 

VAUDE ensures ethical practices for both humans and animals involved in their operation. They work with the Fair Wear Foundation to monitor their final stage of production, ensuring safe working conditions and fair wages for factory workers. They also audit 100% of their producers in high-risk countries. Additionally, VAUDE has a basic policy to support diversity and inclusion in their direct operations and supply chain. Regarding animal rights, they follow the Responsible Wool Standard, appropriately addressing sheep’s welfare and the land they graze on. 

VAUDE donates FairWertung the products that can’t be repaired but are still perfectly functional. In 2021, VAUDE donated products with a merchandise value of approximately €339,000 (approximately $375,000 USD) to the network, which makes clothes affordable via charity shops or second-hand stores.

Tripulse: Activewear Made Sustainable With Certified Eucalyptus Wood Fiber

Tripulse was founded in Sweden in 2019 by Franziska Mesche with a mission to create the most sustainable, health-friendly, and ethical activewear company. Today, Tripulse has become a recognized activewear brand, offering climate-neutral garments that combine quality, comfort, and performance.

“Sustainability is at the heart of everything we do and of every decision we make. It’s part of our DNA.”

Franziska Mesche, Founder of Tripulse

Tripulse ensures sustainability by sourcing low-impact materials, reducing waste, and overcompensating their carbon emission to be climate-positive. Firstly, they use a high proportion of TENCELTM lyocell made with certified eucalyptus wood fibers. Tripulse also opts for ROICA™ V550, a more eco-friendly stretch alternative to spandex (elastane), for the stretch element necessary in gym leggings. Furthermore, the elastane found in a small percentage of Tripulse’s Power III fabric blend consumes less energy, requires lower CO₂ emissions than conventional elastane, and has various sustainability certifications (Bluesign^®, OEKO-TEX®, and REACH). On top of that, they use organic cotton and natural rubber for elements lik ecare labels and waistbands. Secondly, Tripulse reduces waste by designing timeless, versatile, and multifunctional garments that are durable and long-lasting, using recycled and recyclable packaging materials, and keeping clothing with minor blemishes, prototypes, or returned and refreshed clothing in circulation with their ZeroWaste Shop. Last but not least, the brand holds climate action at the center of their operation, measuring, reducing, offsetting, and overcompensating their carbon emissions. On top of using low-carbon materials and reducing waste, they offset more than their emissions in projects preventing deforestation in biodiverse areas. 

Tripulse ensures their ethics by partnering with a factory certified by the Global Organic Textile Standards and paying a living wage in the final stage of their production. They are also transparent about the rest of their supply chain, publicly sharing their suppliers for various components.

On top of that, they offer a take-back program where customers can return their worn-out Iron Roots apparel for the purpose of recycling it into new products. Lastly, to avoid overproduction, they do not offer seasonal collections. Regarding their carbon footprint, Iron Roots manufactures locally to reduce their transporting carbon emissions and offset all those occurring from shipping in their supply chain. 

Iron Roots traces most of their supply chain. The manufacturing stage happens in GOTS and SMETA-certified factories in Greece, North Macedonia, and Portugal. The factory’s workers are paid living wages that average 1.5–1.7 times the minimum wage in their country.

Definite Articles 

Definite Articles ensures their sustainability firstly by creating the planet’s first biodegradable performance wear to reduce plastic waste and associated pollution. In particular, they use the next generation, OEKO-TEX® certified sustainable technology “CiCLO” that enables traditional yarns like nylon and polyester to behave like natural fibers when they end up in the environment and thus biodegrade in two to three years rather than centuries. Additionally, their collection is free of harmful chemicals like BPA and PFAS and partly made with relatively low-impact textiles such as cotton under the Better Cotton Initiative or lyocell. Secondly, Definite Articles reduces their climate impact by keeping their entire supply chain locally in the US for a lower transporting carbon footprint.

Elle Evans, founder of Elle Evans

Elle Evans prioritizes sustainability by reducing the carbon footprint throughout the life-cycle of their products, from sourcing to transporting and packaging. Firstly, their fabrics have a high proportion of ECONYL^® regenerated yarn from nylon waste, avoiding the high-impact virgin nylon while rescuing waste such as finishing nets from the bottom of the oceans and carpets from landfills. Further down the production line, they have their fabrics digitally printed using water-based, non-toxic inks, a process that leaves no ink discarded down drains and no washing required after printing. Afterward, the fabrics are only cut and sewn after a product is ordered to further reduce waste. The final products are wrapped in carry bags made from deadstock fabrics from Elle Evans’ studio and delivered using carbon-neutral couriers Sendle. 

Elle Evans makes their products themselves in-house by the founder/owner and a small team. Regarding their materials, they trace most of their supply chain.

ARMEDANGELS: Sustainable Clothing Brand Plus an Agent of Lifestyle Change 

ARMEDANGELS was founded in Cologne, Germany, in 2007 by Anton Jurina and Martin Höfeler with a vision to use business to protect all life. Today, they are a prominent sustainable fashion brand, pursuing eco-conscious and ethical practices throughout their production chain while being an agent of change—changing culture, consumption, and lifestyle choices. ARMEDANGELS has a GRS-certified activewear collection, combining sustainable material technology and stretch-support know-how to create performance-perfected essentials for activities like yoga, running, or gym workouts. 

“So starting out with the humble tee, we took our oath against wage slavery, chemical shortcuts, and mass-producing pure crap, and transformed ourselves into one of the first clothing brands in all the land to put people and planet first.”

ARMEDANGELS 

ARMEDANGELS ensures sustainability by reducing carbon footprints while enabling people to change lifestyles to fight climate change. The brand innovates to cut down carbon emissions in their supply chain, starting with sourcing a high proportion of eco-friendly materials. Specifically, they use GOTS-certified organic cotton fabrics, GRS-certified recycled fabrics, GOTS-and RWS-certified organic wool fabrics, and FSC/PEFC-certified wood-based fabrics like TENCEL^TM Modal. Additionally, ARMEDANGELS chooses materials with the lowest carbon footprint possible, for example, opting for modal and lyocell over silk or natural fabrics over fossil-based synthetic fabrics while increasing recycled content, such as recycled wool and recycled cotton. For example, within a year, the share of recycled cotton in their DetoxDenim jeans increased from 5% to 37%, with some jeans in the collection containing 100% recycled cotton. Lastly, ARMEDANGELS’s efforts to encourage lifestyle change include care and repair guides to keep garments longer in circulation. They also have a resale platform that facilitates traded-in items to be sold again as second-hand clothes or recycled as fibers for new clothes. 

ARMEDANGELS ensures their ethics by only working with trusted partners to deliver decent wages and workers’ safety. They directly and actively monitor all their suppliers and the suppliers’ nominated subcontractors via on-site and online Internal Due Diligence Check and Self-Assessment, external audits by Fair Wear Foundation (FWF), Global Organic Textile Standard and third-party audits, continuous support, and tailored training programs by third parties. ARMEDANGELS ensures payment of a living wage in part of their supply chain and pays a markup where they notice wage issues via the living wage project. Most importantly, they are fully transparent about the journey from raw material to their products, especially where people and animals are involved, and the impacts of their actions. 

ARMEDANGELS raises funds by donating part of their sales to support various organizations and campaigns. For example, during the COVID-19 pandemic, they raised €745.800 ($790,883.61 USD) for Doctors Without Borders, facilitating isolation wards, COVID-19 clinics, and protective clothing for medical professionals worldwide. Other fundraising projects include supporting the climate movement with German Zero and the Climate Emergency Fund, fighting for equality with UN Women, advocating for fair payment and safe working conditions for Bangladeshi garment workers with the National Garment Workers Federation, and rescuing refugees in the Mediterranean Sea with Sea-Watch.

Furthermore, Happy Earth Apparel is Climate Neutral Certified for reducing and offsetting their emissions. They also use solar energy in their supply chain to reduce their carbon emissions. Regarding emissions that can’t be avoided, they offset through clean energy projects in the US, Uganda, India, and China.

Threads 4 Thought: Everyday Basics Produced Responsibly 

Threads 4 Thought was founded in California in 2006 by husband-and-wife team Eric and Leigh Fleet to create a product that leaves an innately smaller impact on our environment, supports in-need communities, and assists in changing the narrative and understanding of ethical standards within the fashion industry. Today, Threads 4 Thought has grown into a recognized brand in sustainable fashion, offering ethically manufactured apparel you can wear anywhere, anytime.

“From our original designs to our fabrics to the factory floor, we are committed to leaving an innately smaller impact on our planet.”

Threads 4 Thought

Threads 4 Thought promotes sustainability by sourcing a high proportion of eco-friendly materials,including recycled polyester, organic cotton, and modal with Lenzing’s renewable beech tree pulp. For example, the Lunette Sports Bra contains 88% recycled polyester. Further down the life-cycle in manufacturing, they lower their environmental impacts by implementing a dye technology that eliminates all harmful chemicals and reduces water usage during the dyeing process by 95%. They also recycle 80% of their main factory’s industrial wastewater. Additionally, their packing materials are fully FSC-certified, with 90% being WaveBags, which are 100% recyclable, water resistant, and strong. Lastly, 99% of their products are transported by boat rather than air, reducing carbon emissions during the transportation stage.

Threads 4 Thought traces most of their supply chain and reduces their impact through Greenstory. They have a Supplier Code of Conduct that covers all ILO’s Fundamental Freedoms. 

Threads 4 Thought partners with the International Rescue Committee to help people displaced due to various conflicts.

Why Is It Important to Buy Products Made of More Sustainable Fabrics

It is important to buy products made of more sustainable fabrics because a sustainable textile industry has a lower carbon footprint, helps save natural resources, and is better for forests, animals, and humans. 

Buying Sustainable Fabrics Reduces Your Carbon Footprint 

The production of clothing and footwear is estimated to contribute 10% of global greenhouse gas emissions—more than all international flights and shipping combined. If the fashion industry were a country, it would be the fourth largest emitter of carbon dioxide. 

One way to reduce the carbon footprint of the clothes you buy is to opt for sustainable fabrics. Sustainable fabrics, which are often made with natural or recycled fibers, have relatively low carbon footprints compared to petroleum-based fabrics. For example, organic cotton made in the US has a carbon footprint of 2.35 kg CO₂ (per ton of spun fiber)—a quarter of polyester’s carbon footprint.

Buying Sustainable Fabrics Reduces Demand For Natural Resources and Waste Management

The textile industry uses water and land to grow cotton and other fibers. It is estimated that 79 billion cubic meters of water were used for the sector worldwide in 2015. For example, producing a single cotton t-shirt requires as much water as one person drinks for 2.5 years (2,700 liters of fresh water).

Worse yet, the textile economy is vastly more linear than circular: the largest amount of resources used in clothes ended up in landfills (instead of being recycled to remake clothes). According to a report by the Ellen MacArthur Foundation,

• Less than 3% of materials used in the textile economy in 2015 came from recycled sources.
• In other words, more than 97% of resources used in making clothes are newly extracted. 

When clothing items are disposed of within a short period of time—under a year in the case of half of the fast fashion clothes—the natural systems that provide raw materials for fabrics don’t have enough time to recover and regenerate, which could lead to ecological breakdown. 

Sustainable fabrics are made with less water and emissions while lasting longer:

• Because they are durable, you don’t need to buy new clothes too often. 
• Thus, you help reduce the pressure to extract more resources for making new items. 

Similarly, making and consuming sustainable fabrics made with recycled materials reduces the demand for virgin materials while helping tackle waste management. 

Buying Sustainable Fabrics Encourages Sustainable Management of Forests

Sustainable natural fiber fabrics are made with raw materials from forests and plantations that are sustainably managed, such as complying with FSC standards. 

When you buy sustainable natural fiber fabrics, you discourage unsustainable forestry practices like illegal logging. You can help reduce deforestation, biodiversity loss, and the effects of climate change. 

Buying Sustainable Fabrics Encourages Fairer Treatment of Animals 

The fashion industry is rife with animal mistreatment when it comes to making animal-based fabrics like wool or silk. Every year, billions of animals suffer and die for clothing and accessories.

Buying sustainable vegan alternatives can help to reduce the pressure on raising more and more animals to meet the demand for animal-based fabrics while sacrificing their well-being and lives. 

Suppose you have to buy fabrics made with, for example, wool or silk; make sure you only choose brands committed to cruelty-free products. In that case, you help advocate better treatments for animals raised within the textile industry. 

Using Sustainable Fabrics Encourages Fairer Treatment of Textile Workers 

Recent statistics from UNICEF estimated as many as 170 million child laborers worldwide, many of whom were engaged in some form of work in the textile industry. They don’t get paid minimum wages and often work long hours. 

When you buy sustainable fabrics from brands transparent about the working conditions at their factories, you discourage the use of child labor and help promote better working conditions for textile workers.

How Can You Generally Buy More Sustainable Fabrics

The key to sustainably buying fabrics is to check on relevant environmental and original certifications. 

For natural fabrics: 

• Global Organic Textile Standard (GOTS): A globally recognized certification system that ensures a certain threshold of organic content has been met. It covers manufacturing, packaging, labeling, transportation, and distribution (but not what happens in the fields where crops are grown). 
• USDA Certified Biobased Product: The USDA BioPreferred^® Certification is a voluntary certification offered by the United States Department of Agriculture. The certification identifies products made from plants or other renewable materials.
• Ecolabel: Ecolabel is the official European Union voluntary label recognized worldwide for certified products with a guaranteed, independently verified low environmental impact. The label requires high environmental standards throughout the entire life-cycle: from raw material extraction through production and distribution to disposal. It also encourages companies to develop innovative, durable, easy-to-repair, and recyclable products. 

For natural fiber semi-natural/semi-synthetic fabrics:

• Forest Stewardship Council: An FSC certification ensures that the wood (or wood-like material) comes from responsibly managed forests that provide environmental, social, and economic benefits.
  
  There are two types of FSC Certification: 
  • FSC Forest Management Certification, with a focus on the origin of the wood—the forest. 
  • FSC Chain of Custody Certification, which focuses on the path from the forest to the customer’s home. 

• Program for Endorsement of Forest Certification: PEFC’s approaches to sustainable forest management are in line with protecting the forests globally and locally and making the certificate work for everyone. Getting a PEFC certification is strict enough to ensure the sustainable management of a forest is socially just, ecologically sound, and economically viable but attainable not only by big but small forest owners.

For recycled fabrics:

• Recycled Claim Standard (RCS): The Textile Exchange RCS was originally developed as an international, voluntary standard that sets requirements for third-party certification of Recycled input and chain of custody. 
• The Global Recycled Standard (GRS): The Global Recycled Standard (GRS) is an international, voluntary, full product standard that sets requirements for third-party certification of Recycled Content, chain of custody, social and environmental practices, and chemical restrictions. It can be used for any product with more than 20% recycled material.

For all types of fabrics:

• STeP by OEKO-TEX^®: STeP by OEKO-TEX^® is an independent certification system for brands, retailers, and manufacturers from the textile and leather industry. It communicates organizational environmental measures, including reducing carbon footprint and water usage.
• OEKO-TEX^® Standard 100: OEKO-TEX^® labels aim to ensure that products pose no risk to human health (i.e., containing banned chemicals). 

Some certifications that are signaling brands’ efforts toward lowered environmental impacts and a circular economy are: 

• B Corp Certification: The label B Corp is a certification reserved for for-profit companies. Certified holders are assessed on their social and environmental impacts. 
• Cradle2Cradle certification: Cradle2Cradle provides a standardized approach to material circularity. It assesses whether products have been suitably designed and made with the circular economy in mind covering five critical categories: material health, material reuse, renewable energy and carbon management, water stewardship, and social fairness.

Final Thoughts

Activewear is a category of clothing that is often high-impact due to its frequent washing needs and its conventional use of high-impact synthetic fabrics for stretch and moisture wicking. Thus, it is important to shop with ethics and sustainability in mind when choosing your next pair of running shorts or cycling gloves. 

By purchasing activewear from brands that commit to sustainability, you support their mission to create a fairer and less harmful textile industry for all lives on Earth. 

Here is the list (again) of the most sustainable activewear brands:

– Patagonia

– Girlfriend Collectives

– Finisterre

– Wolven

– VAUDE

– Tripulse

– Iron Roots

– Outerknown

– NATASHA TONIC

– Definite Articles

– Vitamin A

– Elle Evans

– ARMEDANGELS

– Happy Earth Apparel

– Threads 4 Thoughts

To make your use of these clothing items even more sustainable, follow these steps:

1. Buy recycled or upcycled activewear made with low-impact materials. 
2. Keep your activewear for as long as possible.
3. At the end-of-life of your activewear, upcycle the materials to extend their usage and arrange for them to be recycled or properly disposed of.

Stay impactful,
