Features 3 of 5
Feature 1 Every Known Supply garment is made from GOTS Certified organic cotton, and the brand also offers regenerative organic cotton certified by the Regenerative Organic Alliance. Known Supply designs its cotton pieces to be recyclable into new fabrics through fibre-to-fibre recycling of like materials such as 100% cotton.
Feature 2 Known Supply produces every organic cotton item at a Fair Trade Certified or direct trade facility to ensure a positive impact on the people making its products. Each Known Supply product carries a QR code through its Meet the Makers programme, letting you scan to meet one of the people who helped make your garment.
Feature 3 Known Supply runs a Second Chance Bag take-back programme in partnership with Homeboy Threads, giving $20 in store credit for returned clothing that is then re-used, recycled fibre-to-fibre, or downcycled for long-term functional uses such as commercial insulation. Known Supply notes that 85% of donated clothing still ends up in landfills, which is why its cotton garments are designed to be recyclable to create new fabrics.

Supply-chain summary Known Supply names the individual person who made each garment, letting shoppers enter the maker's name printed on the product into a Meet the Makers search to see who made it. Known Supply discloses its Fair Trade Certified facilities across Lima in Peru, Gulu in Uganda, several cities in India and Shanghai in China, and holds B Corp certification. Known Supply grew out of the non-profit Krochet Kids intl., founded in Uganda in 2007. Known Supply offers exceptional maker-level cut-make-trim transparency, though it does not publish raw-fibre or cotton origin, mills or dye houses.

H3 Q1: Is [Brand] sustainable / ethical? Is Known Supply sustainable and ethical?
Answer 1 DOCUMENTED FACTS: Known Supply is a Certified B Corp (since 24 July 2019) and California benefit corporation; it uses Fair Trade Certified facilities in India and GOTS-certified organic cotton for nearly all cotton, with some Regenerative Organic Certified cotton in newer styles; every product is hand-signed by an identifiable maker with a public online profile (a genuinely unusual, verifiable tra
H3 Q2: Where is [Brand] made? Where is Known Supply made?
Answer 2 Known Supply garments (apparel) are made in Fair Trade Certified production facilities in India, while its accessories are produced through direct-trade partnerships in Peru and Uganda that the founders originally established via Krochet Kids International. Independent sources describe production as "a small number of facilities in India, Peru, Uganda and other regions." Known Supply's model centres on maker transparency: each product is hand-signed by the person who made it, with an online "Meet the Makers" profile customers can look up.
H3 Q3: Who owns [Brand]? Who owns Known Supply?
Answer 3 Known Supply is an ethical apparel brand launched in 2017 by Kohl Crecelius and Travis Hartanov, the co-founders of Krochet Kids International, and is structured as a California benefit corporation headquartered in Costa Mesa, California. Known Supply is not an independent standalone startup: it grew out of Krochet Kids International (a headwear/accessories brand and social-impact organization the pair co-founded in 2007), and Krochet Kids now "operates as a brand under KNOWN SUPPLY" per Krochet Kids' own November 14, 2017 announcement. Kohl Crecelius is CEO and co-founder of both. No larger corporate parent or acquisition is documented; it appears to be founder-led.
H3 Q4: Is [Brand] legit / worth it? Is Known Supply legit and worth it?
Answer 4 Known Supply is a real, currently-trading legitimate business, not defunct. As of July 2026 its website (knownsupply.com) is live with a "© 2026" footer, active collections, and in-stock, priced products (e.g. Ada Pullover $68, Aja Dress on sale). It is the clothing/apparel brand (verified distinct from unrelated same-name entities) based in Costa Mesa, California, and is listed as active on company databases.
H3 Q5: Is [Brand] fast fashion? Is Known Supply fast fashion?
Answer 5 Known Supply is a slow / small-batch ethical fashion brand, not fast fashion. It focuses on long-lasting, versatile basics and staples (organic-cotton tees, dresses, knitwear) made in a small number of Fair Trade facilities, explicitly positions itself against "disposable (aka 'fast') fashion," and emphasizes traceability with each garment hand-signed by its maker rather than trend-driven, high-volume drops.
Answer 6 Certifications: Known Supply holds documented certifications including Certified B Corporation status (certified July 24, 2019; also legally a California benefit corporation since inception), Fair Trade Certified (Fair Trade USA) production facilities, and GOTS (Global Organic Textile Standard) certified organic cotton for nearly all of its cotton. Some newer styles use Regenerative Organic Certified (ROC) cotton. No OEKO-TEX or European Flax certification is documented for Known Supply..
Answer 7 Known Supply holds the following certifications: Known Supply holds documented certifications including Certified B Corporation status (certified July 24, 2019; also legally a California benefit corporation since inception), Fair Trade Certified (Fair Trade USA) production facilities, and GOTS (Global Organic Textile Standard) certified organic cotton for nearly all of its cotton. Beyond any paper certification, our scan of 283 Known Supply styles found 74.1% is 100% plant fibre, which is the measurable material fact behind Known Supply's claims.
Methodology note (page footer) How we scan. Every figure on this page comes from the Throne Standard scan: we read the fibre composition off each live product on the brand's own site, style by style, and count only single-fibre plant cloth (cotton, linen, hemp) as natural. Animal fibres such as wool, silk and cashmere and plastic-based synthetics such as polyester, nylon and elastane sit outside the plant-fibre figure, and regenerated fibres such as viscose, bamboo, modal and Tencel are counted as semi-synthetic. Percentages are calculated over the styles that state a composition; anything unlabelled is shown separately.
Synthetic % 11.5
Semi-synthetic % 0.8
Answer 8 So many Known Supply basics are pure cotton, but Known Supply's fitted and active styles typically add a small share of synthetic.

How it was read Throne identifies the eligible textile products in Known Supply's catalogue, inspects each product for published material evidence and requires at least 20 scoreable textile SKUs before publishing a brand score. The score uses only products with enough published material information to classify. Brand non-disclosure and technical read failures are reported separately. Non-textile products are excluded rather than counted as a pass or a fail.
