Kent
Rated: Good
Price: $
Location: USA
Quick verdict
Kent is best for eco-conscious consumers who want 100% plastic-free, compostable everyday basics, including underwear, bras, and sleepwear made entirely without synthetics. What makes Kent truly unique is its verified compostability claim: their briefs decompose in approximately 90 days, making them the world's first verified compostable underwear brand. The main caveat is that living-wage claims across the full supply chain remain unverified.

Kent sustainability rating
Our ratings are based on a scale from 1 (We Avoid) to 5 (Excellent). How we rate
Rating breakdown
Uses 100% GOTS-certified organic Pima/Supima cotton sourced from Peru, bio-based elastics from renewable tree resources, and GOTS-certified or natural plant-based dyes. Absolutely zero synthetics, not even 5% spandex in trims. This is an exceptionally rare standard in the underwear market.
Manufactures in a Fairtrade- and GOTS-certified family-owned factory in India that reportedly pays 25% above living wages, plus a family-owned LA factory. However, there is no independent evidence that living wages are ensured across the full supply chain, and the brand doesn't specify what percentage of its supply chain is audited.
All products verified compostable in ~90 days. Carbon-neutral shipping option. Zero-plastic packaging (plant-based, compostable). Organic farming practices support carbon sequestration. Three circularity programs (Compost Club, Recycle Club, Plant Your Pants). Small-batch production avoids overproduction.
Publishes extensive materials philosophy, manufacturing countries (USA, India, Canada for labels), and certification details. Has an Impact Reports page. However, does not publish specific factory names/addresses, aggregate materials breakdown, or specify audit percentages, which limits full accountability.
At ~$24/pair (singles) and ~$63 for a 3-pack, Kent sits at the premium end alongside brands like Organic Basics and Thunderpants. The pricing is justified by genuinely unique attributes (100% organic, zero synthetics, verified compostability). Multi-pack discounts (up to 14% off) help.
What they do well
- World's first verified compostable underwear, independently tested by LA Compost, decomposing in ~90 days. No competitor matches this end-of-life innovation.
- Absolute zero-synthetic standard across every product, including elastics and thread. Bio-based elastics from renewable tree resources replace spandex entirely. This is extraordinarily rare in the underwear category.
- Three distinct circularity programs: Compost Club (brand take-back for farm composting, $10 store credit), Recycle Club (accepts non-Kent items for recycling), and Plant Your Pants (home composting guidance). Earned a Fast Company World Changing Ideas 2023 honourable mention.
- Strong certification stack spanning GOTS, OEKO-TEX, USDA BioPreferred, Fairtrade, and 1% for the Planet, with the cotton farm itself being B Corp and WFTO certified.
- Shark Tank validation: secured $200K from Daymond John (Season 14 premiere), with competing bids from Robert Herjavec and Lori Greiner. Featured in Financial Times, Forbes, Vogue, Refinery29, and Business of Fashion.
Room for improvement
- Labour transparency is the weakest link. There is no independent verification of living wages across the full supply chain. The brand claims its Indian factory pays 25% above living wages, but this isn't third-party confirmed at all tiers.
- No published aggregate materials breakdown or formal annual impact report, despite having an Impact Reports page on the site.
About Kent
Kent was founded in 2020 by Stacy Grace, who spent over a decade in sustainable fashion working with TOMS, Wrangler, and Timberland. Frustrated that 99% of underwear on the market contained synthetics, she set out to create the world's first truly plastic-free, compostable basics line. The brand initially produced organic silk underwear sold through J Crew and Selfridges before pivoting to its current 100% GOTS-certified organic Pima cotton focus.
All cotton is sourced from Peru, the only region growing this specific extra-long-staple variety, from farms certified by GOTS, the World Fair Trade Organization, and B Corp. Manufacturing takes place in a Fairtrade- and GOTS-certified family-owned factory in India and a family-owned facility in Los Angeles. Kent uses bio-based elastics derived from renewable tree resources instead of spandex, GOTS-certified dyes for core colours, and natural plant-based dyes (from fruits, flowers, and minerals) for limited editions. Packaging is entirely plant-based, acid-free, and compostable with soy-based inks.
Shipping is free in the US over $75, with carbon-neutral options at checkout, and the brand ships to Canada, the UK, Australia, and Europe. Returns follow a 14-day window with a $10 restocking fee; international returns are not accepted. Pricing sits at the premium end of sustainable underwear, roughly comparable to Organic Basics (~$22–35/pair) and Thunderpants (~$25–32/pair).
The premium reflects the zero-synthetic formulation, verified compostability, and circularity programs that no competitor currently matches. Kent was rebranded by Red Antler (the agency behind Allbirds, Casper, and thredUP) and its founder is a Tory Burch Fellow.
