10 Most Sustainable Summer Clothing Brands: The Conscious Consumer’s Guide
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?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
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?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
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, whether for the coldest or the warmest weather.

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.

peony: Carbon-Neutral Luxury Swimwear Made From Repurposed Waste


“Our approach is to create consciously, engage in ongoing reflection and continually drive progress towards sustainability, circularity, inclusivity and transparency..”
peony
🌎
How do they ensure their sustainability?
peony ensures their sustainability by sourcing eco-friendly materials for textiles and packaging while reducing plastic waste.
- Specifically, their swimwear main fabrics and linings are created in-house with recycled content, which includes REPREVE® yarn made from 100% recycled plastic bottles and ECONYL® yarn, a 100% regenerated nylon fiber made from nylon waste that would otherwise pollute the earth, such as fishing nets, fabric scraps, and carpet flooring. So far, their use of recycled swimwear fabrics has diverted approximately 104,975 lbs of post-consumer waste from landfills. For their resort wear, the brand also sources low-impact fabrics, including GOTS-certified organic cotton, European Flax®-certified linen, EcoVero®—a responsibly sourced viscose yarn made by Lenzing with EU Ecolabel‘s stamp of approval, recycled polyester, and hemp. Linen and organic cotton accounted for the largest percentages of fibers in their 2022 resort wear collection: 37% and 35%, respectively. peony also opts for low-impact packaging, using only recycled, compostable, and reusable materials. Their orders are wrapped in recycled, compostable, and FSC-certified tissue paper and sent in mailer bags made from waste, using only renewable solar power—no water, acid, or bleaches. Their garment components include swing tags made from recycled and FSC-certified wood, swimwear hygiene liners made from FSC-certified wood-based bioplastic, and compostable and biodegradable bags for bikini straps.
- Secondly, peony designs for circularity, which means that garments are made to be worn, reused, and recirculated for as long as possible. They achieve that by sourcing the highest quality fabrics and using construction techniques that extend the life of each garment. The brand also aims to create pieces that transcend seasons so you can use them in your wardrobe season after season. When a piece is at the end of its life, peony will take it back for responsible reuse or recycling.
- Lastly, all of peony’s printed fabrics are digitally printed, reducing fabric waste and water consumption.

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 landfill (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 Canadian 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
The fast fashion industry has pushed for many summer clothing items to be trend-dependent and easily replaceable. Yet, the environmental impacts of making and landfilling clothes can be enormous, especially with certain materials. Thus, it is important to shop with ethics and sustainability in mind when choosing your next item of summer clothing.
By purchasing summer clothes 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 summer clothing brands:
- Christy Dawn
- Vitamin A
- éclipse
- The Classic T-Shirt Company
- All The Wild Roses
- Altar
- peony
- Harvest & Mill
- Neu Nomad
- Passion Lilie
To make your use of these summer clothing items even more sustainable, follow these steps:
- Buy second-hand, recycled, or upcycled clothes made with low-impact materials.
- Keep your clothes for as long as possible.
- At the end-of-life of your clothes, upcycle the materials to extend their usage and arrange for them to be recycled or properly disposed of.
Stay impactful,
