Cone Denim

Cone Denim is a B2B denim mill rather than a consumer clothing brand, so it is not scored by our plant-fibre standard. See what it makes and how it is sourced, checked from source.

The brand

About Cone Denim

Cone Denim makes its denim fabric from certified organic cotton grown without pesticides, herbicides or synthetic fertilizers, alongside recycled cotton from post-industrial and post-consumer waste, BCI and US Cotton Trust Protocol cotton, and a hemp denim collection sourced from the US, France or China. Lenzing wood-based TENCEL, MODAL and TENCEL x REFIBRA fibres feature in the range as 100% bio-degradable fibres produced from sustainably sourced wood, and the mill also uses REPREVE recycled polyester made from post-consumer plastic bottles, GRS-certified recycled elastane such as Creora Regen and Lycra EcoMade, plus CiCLO fibres.
As a denim mill and fabric supplier, Cone Denim sells its denim fabric to garment manufacturers rather than making finished clothing, operating from Greensboro, NC with mills in Parras and Yecapixtla in Mexico and Jiaxing in China. A closed-loop recycling process in Mexico produces recycled yarn with a small footprint, while the Parras mill runs a Zero-Liquid Discharge wastewater recovery system and the operations draw on a cogeneration system and solar power that generates 9 MWH of electricity annually.
Beyond its recycled and biodegradable fibres, Cone Denim uses USDA BioPreferred certified Natural Indigo dye and sustainability processes such as Flash Finish, which saves an average of 83% of water compared with traditional denim finishing. Under its Sustainblue programme, Cone Denim holds validated Science Based Targets to reduce scope 1 and scope 2 GHG emissions 46.2% by 2030 from a 2019 base year and aims for 100% preferred and low climate impact fibres by 2030.

Where this brand isn't perfect

Straight talk

Where Cone Denim isn’t perfect

Check firstNot a certified B Corp

Cone Denim is not a B Corp. The brand-level labels are thinner than the product-level ones.

Check firstThe farm and factory aren't named

Cone Denim doesn't publish its specific farm or factory names. Supplier disclosure: partial.

Skip it ifNo named cotton farm (origin verified scientifically, not farm-listed); no full supplier list beyond its own mills; being a fabric mill, garment-stage transparency depends on its brand customers.

What the label won’t tell you

The questions sensitive skin actually asks, answered

2 of 6 styles scanned, no sampling 0% plant · 100% synthetic PFAS-free (verified) ✓ read from the live product feed, not the marketing page
Are there hidden chemicals against my skin?

Cone Denim is PFAS-free (verified). 2 of 6 styles scanned: zero PFAS, zero formaldehyde, dye process on record: Low-impact / GOTS-certified dyes

Is "sustainable" just greenwashing?

“Eco” and “green” have no legal meaning, and thousands of unverified claims flood the market. We scanned 6 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: 4 products wouldn’t scan cleanly. Every one is named in the sourcing ledger below.

Is "100% cotton"
actually
100% cotton?

Most “cotton” underwear hides elastane or spandex in the trims. We read the stated fibres on 2 of 6 styles, thread by thread: 0% plant, 100% synthetic.

Will the elastic bring me out in a rash?

Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: No elastane.

Where's it really made,
and by whom?
Named farm and factory
GOTS chain of custodyTraceable back to the cotton

Traceability on record: Not disclosed; factory: Parras and Yecapixtla, Mexico; HQ Greensboro, North Carolina, USA. We publish the full sourcing chain and the honest red flags, including where sources conflict.

Am I shedding microplastics onto my body?

Synthetic underwear sheds plastic fibres onto your skin and into the water with every single wash. Cone Denim is 100% 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.

Cone Denim (part of Elevate Textiles) is a B2B denim fabric mill that discloses its own mill locations at Parras and Yecapixtla, Mexico, both Recycled Claim Standard certified, and is the first mill globally to provide court-admissible cotton origin traceability using Oritain’s scientific verification. It offers organic, recycled, BCI, U.S. Cotton Trust Protocol and regenerative (regenagri) cotton and has pledged to source verifiably sustainable cotton, though as a mill it does not publish a farm list or a downstream supplier list.

Sourcing flags & notes: No named cotton farm (origin verified scientifically, not farm-listed); no full supplier list beyond its own mills; being a fabric mill, garment-stage transparency depends on its brand customers.

What this meansThese products carry no fibre composition the brand publishes anywhere we can read. They are counted in the catalogue total but excluded from the fibre percentage, and linked so you can check them yourself.
Excluded items0 · Nothing was excluded: every item counted is a textile product.
Brand site readableYes

How it was read: Every product listed in Cone Denim's live catalogue is retrieved and its stated fibre composition read individually, from the Cone Denim product page, Cone Denim's own product data and its material labels. A fibre percentage for Cone Denim is published only when 100% of the Cone Denim catalogue has been read. Items Cone Denim 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.
