Affiliate Disclosure

Hey fellow impactful ninja ?

You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.

  • Most of these links are informational-based for you to check out their primary sources with one click.

  • But some of these links are so-called "affiliate links" to products that we recommend.

Why do we add these product links?

First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.

And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.

What do these affiliate links mean for you?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.

What do these affiliate links mean for us?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.

What does this mean for me personally?

You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.

Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

Stay impactful,

Amid growing concerns about the textile industry’s environmental impact, there is pressure to find greener clothes for your wardrobe, from outerwear to loungewear. 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 loungewear brands?

The most sustainable loungewear brands include hernest project, Subset, and Underprotection, which use low-impact natural materials, reduce carbon emissions, and strive for textile circularity. In addition, The Ethical Silk Company and Boody commit to waste reduction and ethical manufacturing.

Whether you are searching for a sweatshirt or a set of pajamas 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 loungewear brands and how they ensure sustainable, ethical practices. 

Here’s How We Selected the Most Sustainable Loungewear Brands

The sustainability of loungewear depends mostly on the fabric used, whether it is synthetic or natural, plant-based or animal-derived. 

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. 

These Are the 15 Most Sustainable Loungewear Brands

Overall, these loungewear brands are sustainable. Yet, they take various approaches to reduce environmental impacts and uphold ethical standards. Let’s dive into each brand and find out more.

hernest project

🌎

How do they ensure their sustainability?

hernest project ensures sustainability by sourcing a high proportion of low-impact materials, reducing textile waste, and offsetting carbon emissions to reach carbon neutrality. Firstly, all their fabrics bear OEKO-TEX® STANDARD 100 certification and feature Bluesign®-approved dyes. Low-impact plant-derived and plant-based TENCELTM, recycled cotton, and organic cotton account for the highest proportions of their collection (37%, 21%, and 21%, respectively). Additionally, they lessen the burden on earth resources by using recycled fabrics, including recycled lyocell, recycled linen, and recycled spandex. Regarding packaging, hernest project uses compostable garment protectors, brief liners, eCom mailers, and organic cotton brand tags. Secondly, they cut down textile waste by operating on limited runs, employing cutting-edge and computer-aided programs to minimize offcuts in the production process, and having their production supplier recycle all offcuts. Excess fabric is made into scrunchies. Additionally, hernest project designs are based on slow-fashion principles of timelessness and versatility. They strive toward circularity by partnering with Treet to facilitate the sale of pre-loved garments. Last but not least, they invest in offset projects such as renewable energy, forest conservation, and energy efficiency to ensure that every item ordered and sold on their site is carbon neutral

Subset

Subset prioritizes sustainability by sourcing a high percentage of low-impact fabrics, offsetting carbon emissions, and facilitating underwear recycling. Firstly, they use GOTS-certified organic cotton, TENCEL™, recycled polyester, and regenerated and recycled nylon to reduce environmental impacts. For example, the Tank Bralette contains certified organic cotton (95% of the fabric), recycled nylon (83% of the straps), and TENCEL™ (69% of the band). Organic cotton, in particular, accounted for 92,1% of their fiber portfolio for 2022. Secondly, they reduce the impact of their carbon emissions with offsetting projects verified by Climate Neutral. For example, in 2022, they supported clean energy projects in India and Kenya. More importantly, they find ways to reduce their carbon footprint, such as using solar-powered energy in their supply chain and localized sourcing. Thirdly, in 2018, Subset launched the world’s first recycling program to save underwear, socks, bras, and tights from ending up in landfills. In 2022, they took back nearly 1 million of their own clothing items, as well as those of other brands.

🌐

How do they ensure their ethics?

Subset ensures their ethics by being transparent about their supply chain, all the way from farming to ginning, spinning, knitting, finishing, and packaging. Much of their supply chain is certified by Fairtrade International – Small Producers Organisations and Global Organic Textile Standard (GOTS). They also ensure that workers at their suppliers are paid a living wage. Regarding the impact of their operation, on each product page, Subset discloses the item’s impact, including not only carbon emission (which is offset) but also the reduction of water usage and synthetic pesticides thanks to their use of organic cotton.

Logo for Underprotection
Screenshot of the Underprotection front page

 “We always strive to make the most sustainable choices even if it is not necessarily the most economically sensible choice, but for us, it is not only a business, it’s a lifestyle and a belief that the future must and can be greeners. It is our goal to always improve – in everything we do

Stephan Rosenkilde, Co-Founder of Underprotection

🌎

How do they ensure their sustainability?

 Underprotection ensures their sustainability by sourcing low-impact textile and packaging materials, prolonging their garments’ lifespan, and striving toward textile circularity. Firstly, they use a high proportion of eco-friendly fabrics, including TENCELTM Lyocell, organic cotton, recycled wool, and RWS-certified responsible sheep wool. All their synthetic fabrics come from recycled sources with the Global Recycle Standard certification, be it polyester, nylon, or elastane (spandex). On top of that, Underprotection also has fabrics made by utilizing by-product waste (banana leaves from the fruit industry and sour milk from the milk industry), helping to cut down waste and lower their environmental impacts. Regarding packaging materials, they opt for recycled or biodegradable materials. Secondly, the brand designs their products with quality and durability in mind to make them last, offers guaranteed repairs within the first two years, provides first-aid rewards for customers who fix up items themselves instead of replacing them, and equips consumers with detailed wash and care instructions for various types of fabrics. All these efforts aim to extend the lifespan of a garment and reduce its environmental cost. Thirdly, regarding their efforts toward textile circularity, they have a take-back program to give worn-out Underprotection pieces a second life, and an Upcycled collection that utilizes returned Underprotection products through their Take-back program, which covers leftover fabrics and discarded items. Last but not least, their main supplier uses solar-powered energy and harvests rainwater.

🌐

How do they ensure their ethics?

Underprotection ensures their ethics by holding a transparent and responsible supply chain. They bind their suppliers with a Code of Conduct, which covers all of the ILO’s Fundamental Principles and Rights at Work. Their suppliers have certifications that guarantee proper working conditions and a fair wage, including WRAP (Worldwide Responsible Accredited Production), Sedex, GOTS, and BSCI (Business Social Compliance Initiative). Underprotection also audits most of the final stage of production.

🤝

Are they part of any giving-back programs?

Underprotection partners with various organizations to give back to underprivileged communities and the Earth. For example, they plant a fixed 150 trees every month in their partnership with Treeapp. Another example is their partnership with the ReSea Project, an organization on a mission to end the ocean plastic crisis.

The Ethical Silk Company: Silk Clothing and Bedding Made Ethically and Eco-Consciously 

Logo for The Ethical Silk Company
Screenshot of the Ethical Silk Company front page

“Embracing this natural fabric (silk), our products combine a love for quality goods and sustainable practices as luxury and practicality are celebrated and embodied.”

The Ethical Silk Company 

🌎

How do they ensure their sustainability?

The Ethical Silk Company ensures sustainability by minimizing waste, using low-impact dyes, and recycling process water. They avoid large inventory and associated waste by keeping the production runs short and only repeating the runs when demand dictates. Old stock is repurposed into smaller items, so each piece of silk is carefully utilized. Patterns are placed on fabrics carefully to keep wastage minimal during production. During the dyeing step of manufacturing, the brand focuses on lowering the environmental impact by eliminating high-impact AZO dyes. Additionally, all water used is treated with a water filtration system to remove the dye residue and is recycled for fabric washing. Their manufacturing partner also has a rainwater catchment system to use in fabric processing. When the season allows (meaning there is no monsoon), their silk can be block printed by hand and left to dry naturally outside, saving process energy and lowering carbon emissions. Lastly, The Ethical Silk Company sources responsible packaging for their silk products, including compostable, corn-based clear bags from Ecoland, recycled and recyclable mailers from Lil Packing, and tissue paper wrapping. 

🌐

How do they ensure their ethics?

The Ethical Silk Company works with a Fair Trade tailoring unit to make their products, ensuring fair labor standards, including but not limited to clean and safe working conditions, payment of a living wage, no child labor, and no discrimination. Regarding animal welfare, The Ethical Silk Company exclusively sources mulberry silk extracted from a cocoon after the moth has left it, as opposed to the cruel practice in conventional silk manufacturing in which the cocoons are boiled to prevent the moths from breaking the silk filament as they emerge. 

🤝

Are they part of any giving-back programs?

Since their inception, The Ethical Silk Company has committed to donate 10% of their profits to charitable causes. Currently, the charities of choice are Jeevan Jyothi AIDS Centre in Theni, India, which works to support those living with HIV and AIDS, and Focus Ireland, a charity preventing people from becoming, remaining, or returning to homelessness.

Their cotton fibers are organically grown and certified by the Global Organic Textile Standard. Boody also has a zero-waste design, which enables knitting garments in tubes, leaving behind very little fabric wastage. Lastly, they encourage recycling of Boody’s ready-to-retire apparel by partnering with UPPAREL to launch The Goodness Loop. This platform enables consumers to buy a return shipping label, which starts the recycling process, and get a gift voucher to redeem on Boody’s new products. 

🌐

How do they ensure their ethics?

Boody enforces fair labor practices by upholding suppliers to their Code of Conduct, which covers four of the ILO’s Fundamental Principles and Rights at Work. They also trace most of their supply chain. Lastly, the suppliers in their final production stage are certified by the Worldwide Responsible Accredited Production (WRAP).

Additionally, they reduce the impact of using wool by opting for the hair of “gentle grazers” like llamas or blending wool with lower-impact materials (such as cashmere and linen). On top of that, aiayu’s Eri silk is made by silkworms fed with castor leaves instead of mulberry leaves. Unlike mulberry cultivation in conventional silk production, castor cultivation in the sourcing area is gentler for the land because these trees require no irrigation, fertilizer, or pesticides. Further down the life-cycle in the manufacturing stage, aiayu reduces their impact by keeping many knits undyed to lower the chemical usage, using renewable energy in their supply chain to cut down their climate impact, and employing a closed-loop system to reduce water use. Lastly, they help prolong their products’ lifespan with complimentary repair service, reducing the life-cycle’s environmental impact.

How do they ensure their ethics?

aiayu traces most of their supply chain. To ensure safe and ethical working environments, they opt to work with production partners with leading social responsibility certifications, including SA8000, BSCI, and WRAP. Regarding animal welfare, they use eri silk, sometimes called “peace silk,” as the silky cocoons are only harvested after the moths have naturally emerged from them, in contrast to the cruel practice in conventional silk production.

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

It is important to buy products made from 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 alike. 

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 plant-based fabrics are made with raw materials from forests and plantations that are sustainably managed, such as complying with FSC standards

When you buy sustainable plant-based 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 plant-based semi-natural/semi-synthetic fabrics:

  • 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

The sustainability of loungewear depends mostly on the fabrics used. Generally, plant-based fibers cultivated organically are the most sustainable option for loungewear. 

By purchasing loungewear 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 loungewear brands: 

  • hernest project
  • Subset
  • Underprotection
  • The Ethical Silk Company
  • Boody
  • Tentree
  • Organic Basics
  • Araks
  • Hara the Label
  • Printfresh
  • Pact
  • Noctu
  • Proclaim
  • aiayu
  • YesAnd

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

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

Stay impactful,
