The Most Sustainable Underwear Brands

Manufacturing underwear requires a fair amount of resources — from growing and milling cotton to powering the factories to cut and sew them, and finally transporting them to you. If you want to choose underwear brands that use resources wisely, you’ve come to the right place.

To choose the most sustainable underwear, we vetted over a dozen climate-friendly brands based on supply chain transparency, emissions tracking and reduction, and circularity. We also looked into labor and ethics, packaging and waste, and other environmental efforts. Based on our sustainability criteria, we ranked brands as Good, Better, Best, or Avoid.

Before You Buy: Believe it or not, even if your underwear is on its last thread, it could still have plenty of life left in it. 

Textiles make up a sizeable chunk of our landfills, contributing to microplastic waste and methane. When you’re done with your underwear, you can send them to Subset or Trashie for textile recycling. These companies will capture whatever fibers can be reused in new garments, and responsibly recycle the rest.

Subset’s underwear is a thoughtful basic with several styles for women and men, and a decent range of colors.

Over 90% of Subset’s material profile is GOTS Certified Organic cotton, which is a natural and eco-friendly fiber. Subsets’s sustainability efforts are grounded in materials and that expands to packaging too.

Lightly used bras are cleaned, sterilized and donated to communities in need. Other innerwaer is sorted by material. Garments that are predominantly cotton are made into recycled yard for apparel manufacturing. Garments made with predominantly synthetic fabrics are broken down into fiber lint to be used in furniture, insulation, and more.

Quality: ★★★★★ Recommend to a friend: ★★★★★ 

Pros: Love the materials and fit of Subset's underwear (hi-rise briefs in particular). Been purchasing them since 2021 in all the lovely colors they have! Bonus points it's a female-founded brand.
Cons: Underwear does stretch out a bit. Subset does recommend handwashing and air drying them (this is the preferred washing method for all delicate fabrics really).

Pros: I love that these are 95% organic cotton. I prefer high-cotton content underwear for the breathability, and these definitely fit the bill! I've tried multiple styles and find them all very comfy and wearable.
Cons: Because they have such a high cotton content, they do seem a bit prone to stretching. This hasn't really been too much of an issue for me yet.

Quality: ★★★★★ Recommend to a friend: ★★★★★ 

Pros: This is my go-to everyday underwear. I love that it's 100% cotton, hugs and fits well, and feels good on my skin. It's well-made and have lasted me through the years. It's almost seamless too, which I love especially when I do hot yoga.
Cons: wish there are more high leg cut styles for underwear. Those styles are just more flattering.

  • Price Point: $15-18/pair (as of June 2024)
  • Locations: HQ in Canada; manufacturing in Bangladesh, China, India, Indonesia, the Philippines, Turkey, and Vietnam.

Tentree’s underwear collection is pared down, but focuses on the tried-and-true styles: bikini and thongs for women; boxer briefs for men. There are three colors for each style. It’s worth noting that their underwear sizing only goes up to XXL.

  • Materials: About 60% of Tentree’s material profile is organic cotton or cotton in conversion. When it comes to packaging materials, Tentree has made strides to reduce plastic by replacing plastic tag fasteners with organic cotton string, and eliminating individual poly bags on 85%-90% of its products in distribution. The mailers used for shipping to customers are made from 100% post-consumer recycled plastic.
  • Emissions: As a Climate Neutral Certified brand, Tentree measures, reports, and offset its corporate carbon footprint which includes the energy used for its headquarters and the emissions of all the goods and services used by its corporate team.

Other brands we recommend

We chose our top picks to offer you a variety of underwear style and prices, but if these don’t fit your needs or you want to explore more options, here are more brands we recommend:

Best Brands

  • MATE the Label: MATE the Label measures and publishes a breakdown of its carbon emissions and has already taken measures to reduce its impact by using natural, low-impact materials, using renewable energy in manufacturing, engaging in fabric waste-reduction efforts, and launching the circular “Detox Your Closet” take-back program. We are also impressed by their commitment to fair labor and more sustainable packaging. But at $28 a pair, they are a bit a bit pricey.
  • Etiko: We love that Etiko transparently reports its carbon emissions and focuses on using eco-friendly materials, like GOTS-certified cotton and FSC certified natural rubber. It’s even working towards becoming fully vegan. If you're based in Australia, they would be a great choice.
  • Dedicated: Dedicated has built its brand and business model around sustainable fashion, prioritizing transparency, certified low-impact and natural fibers, and ethical labor throughout their supply chain. The brand also tracks its progress by measuring and reporting the breakdown of company carbon emissions. We'd love to see Dedicated move toward plastic-free packaging.

Better Brands

  • Pact: We love that Pact measures and offset the emissions of its products and company operations, and its commitment to using GOTS-certified organic cotton. The brand also minimizes plastic in its packaging. However, we'd like to see more transparency around their supply chain and labor practices, as well as their continued plans for reducing greenhouse gas impact.

How We Evaluate Brands

Commons helps people tap into the power of their collective spending choices to lower global emissions. When we evaluate brands, we’re carefully evaluating the actions they’re taking to meaningfully measure and minimize the carbon emissions associated with their products.

Transparent Supply Chains and Reporting

Openness and transparency encourage trust and build accountability. We review publicly available information, including sustainability reports, supply chain partner information, certifications, and partnerships. If this information isn’t available, we don’t include these brands in our top picks.

Emissions Tracking

We look for brands that measure and share the footprint of their company and/or products. When a company understands what its biggest emissions drivers are, it can make plans to address these drivers while also demonstrating progress against these plans. This involves:

  • Measuring their footprint, ideally in collaboration with a third-party partner.
  • Reporting their footprint publicly, ideally sharing the breakdown of their carbon drivers.
  • Taking ownership of their emissions by compensating their footprint with verified, high-quality offsets.

Meaningful Carbon Reduction Efforts

We look for actions that address the most important drivers of the company’s footprint. For clothing, this includes:

Materials: Certifications are important to understand the sustainability of a material and its processing. A couple of key ones we look for are:

  • Global Organic Textile Standard (GOTS): A processing standard for organic fibers that tracks the entire supply chain with environmental and social criteria.
  • Global Recycled Standard (GRS): A voluntary product standard for tracking and verifying the content of recycled materials in a final product. This is especially prevalent for brands using recycled plastic bottles.

Energy: We look for brands using renewable energy and/or engaging with their supply chain partners to support decarbonization of their facilities and manufacturing processes.

Slow or Circular Business Models

Our fashion brand top picks fundamentally shift from fast fashion towards slow fashion and circularity. Evidence of slow or circular business models include:

  • Offering take back and/or recycling programs for their products.
  • Recycling or upcycling fabric scraps, rather than letting them go to waste.
  • Focusing on timeless pieces and infrequent collection releases instead of pushing trends.
  • Engaging in made-to-order or batch manufacturing.

Community and Environmental Efforts

Although we prioritize carbon-related criteria in our rankings, there are other important factors that determine how a brand treats people and the planet. Some of these include:

  • Labor and ethics: Fair Trade certifications and a comprehensive Supplier Code of Conduct (audit for factors like a living wage and safe working conditions)
  • Packaging and waste: plastic-free, FSC-certified packaging that is recyclable and recycled
  • Other community and environmental efforts: This can include donation programs with nonprofit partners, projects that uplift communities near their supply chain partners, and more.

Commons’ Brand Ratings

  • Best: Best brands are measuring, reporting, and actively reducing their emissions. They don’t have to be perfect, but they must have evidence of progress and of tailored strategies to continually improve their footprint.
  • Better: Brands must meet more than one of our climate-related criteria. For example, a brand may not be measuring its footprint, but they are making earnest efforts to address the common drivers of emissions for clothing companies.
  • Good: Brands must meet at least one of our climate-related criteria.
  • Avoid: Brands that meet none of our climate-related criteria.

Brands to Avoid

The business model of fast-fashion brands relies on overconsumption, unethical labor, and fossil-fuel-based fabrics. We recommend avoiding these brands when buying underwear or other clothing:

  • Shein
  • H&M
  • Zara
  • Forever 21
  • Uniqlo
  • Mango
  • ASOS
  • Temu
  • Amazon and Amazon Basics
