Who’s behind it
Sourcing
Getting It
PrAna is not GOTS certified as a company, but uses GOTS certified organic cotton.
prAna is not a B Corp. The brand-level labels are thinner than the product-level ones.
Flagged in the sourcing ledger before you buy.
What the label won’t tell you
prAna is PFAS-free (brand claim). 44 of 213 styles scanned: zero PFAS, zero formaldehyde, dye process on record: Low-impact / GOTS-certified dyes
“Eco” and “green” have no legal meaning, and thousands of unverified claims flood the market. We scanned 213 styles from the store’s own product feed and publish a score only at full coverage. We read certificates, not adjectives.
And nothing is hidden: 178 products wouldn’t scan cleanly. Every one is named in the sourcing ledger below.
Most “cotton” underwear hides elastane or spandex in the trims. We read the stated fibres on 44 of 213 styles, thread by thread: 20% plant, 80% synthetic.
Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: Elastane. Spandex, flagged red in the Skin-Safe section above.
Traceability on record: Tier 1 only; factory: Tier 1 factory locations reported disclosed (name, location, worker count, Fair Trade status); live page unavailable at research time. We publish the full sourcing chain and the honest red flags, including where sources conflict.
Synthetic underwear sheds plastic fibres onto your skin and into the water with every single wash. prAna is 80% synthetic, so yes. These styles shed. Wash cool, use a guppy bag, and favour the plant-fibre options in the range.
Sources: consumer research on formaldehyde in easy-care fabrics (~9% of people react), PFAS in water- and stain-resistant finishes, and hypoallergenic underwear for eczema and contact dermatitis.
Confirmed at the source

The complete clothing data behind the score
Where the materials come from, who makes it, and how traceable it is.
prAna, owned by Columbia Sportswear, discloses its Tier 1 final-production factories with names, locations, worker counts and Fair Trade status, and the majority of its sewing factories are Fair Trade certified (targeting 100% by 2028). prAna uses GOTS organic and Regenerative Organic Certified cotton and bluesign-approved fabrics, but does not disclose Tier 2-4 suppliers (mills, dye houses, spinners) or the farm/country origin of its fibres. prAna scored only 21-30% in the Fashion Transparency Index, indicating strong first-tier but weak deeper-chain transparency.
How it was read: Every product listed in prAna's live catalogue is retrieved and its stated fibre composition read individually, from the prAna product page, prAna's own product data and its material labels. A fibre percentage for prAna is published only when 100% of the prAna catalogue has been read. Items prAna sells that carry no clothing textile, such as gift cards, packaging, jewellery and homeware, are excluded from the percentage rather than counted as a pass or a fail.
Why excluded: Nothing was excluded: every item counted is a textile product.
