About Sumarpo

Sumarpo has been a member of 1% for the Planet since 2021, committing to donate 1% of its annual sales, rather than profits, to environmental causes.

Sumarpo lines its wetsuits with recycled fabrics certified to the OEKO-TEX Standard 100, which verifies the material is free from harmful and toxic substances.

Where this brand isn't perfect

Check firstNot a certified B Corp

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

Skip it ifManufacturing country/factory entirely undisclosed; limestone-neoprene supplier unnamed; '100% ECO' umbrella claim with third-party verification only on the lining (Oeko-Tex); inconsistent corporate-origin story (UK studio vs Southern California) with no stated production base

Flagged in the sourcing ledger before you buy.

What the label won’t tell you

The questions sensitive skin actually asks, answered

✓ 218/218 styles scanned, no sampling ✓ 0% plant · 100% synthetic ✓ Unknown ✓ read from the live product feed, not the marketing page

?Are there hidden chemicals against my skin?

~9% of people react to formaldehyde, common in wrinkle-free and easy-care finishes.

✓Sumarpo is Unknown. Dye process on record: see the sourcing ledger. We record the dye process and chemical flags for every brand.

🚫 Unlock the non-toxic checker

?Is “100% cotton” actually 100%?

Most “cotton” underwear hides elastane or spandex in the waistband, exactly what sensitive skin reacts to.

✓We read all 218 styles individually: 0% plant, 100% synthetic. Even the elastics are bio-based, not spandex. We flag any style whose description hints at a trim.

🔒 See the full fibre breakdown

?Is “sustainable” just greenwashing?

“Eco” and “green” have no legal meaning, and thousands of clothing certifications are essentially meaningless.

✓We scanned 218 styles from the store’s own product feed and publish a score only at full coverage.

✓ See how it was verified

?Will the elastic bring me out in a rash?

Latex and rubber in waistbands are a top trigger for contact dermatitis and latex allergy.

✓0% plant, 100% synthetic across the catalogue means the elastics aren’t spandex. Set your allergy profile and we only show you brands that clear it.

🧪 Build your Skin-Safe Profile

?Am I shedding microplastics onto my body?

Synthetic underwear sheds microplastics into skin and water with every wash.

✓0% plant fibre, plastic-free, so there’s zero synthetic to shed. Every style read individually, no sampling.

🔄 Find a plant swap for anything synthetic

?Where is it really made, and by whom?

“Ethical” brands rarely name the farm or factory, so wage and safety claims cannot be checked.

✓We publish the full sourcing chain, farm and factory certifications, traceability level and the honest red flags, including where sources conflict. Traceability on record: Not disclosed; factory: Not disclosed (manufacturing location never stated on any source found).

🧵 Read the sourcing ledger

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.

Sources checkedChecked: the site's sitemap.xml; each product's own page and product data.

Sumarpo markets itself as ‘the first 100% ECO triathlon wetsuit brand’ and gives good material-level detail: limestone neoprene, non-benzene/water-based glues, an Oeko-Tex recycled lining, FSC packaging, 1% for the Planet membership and TerraCycle wetsuit recycling. However, Sumarpo does not disclose where its wetsuits are manufactured, names no factory, and names no material supplier for its limestone neoprene. Sumarpo’s transparency is strong at the material-claim level but effectively absent at the supply-chain level.

⚑ Sourcing flags & notes: Manufacturing country/factory entirely undisclosed; limestone-neoprene supplier unnamed; '100% ECO' umbrella claim with third-party verification only on the lining (Oeko-Tex); inconsistent corporate-origin story (UK studio vs Southern California) with no stated production base

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 items7 · Items with no clothing textile to rate. Gift cards, packaging and returns kits, jewellery, homeware, toys, body care and checkout line-items. Removed from the fibre percentage rather than counted as a pass or a fail.

Brand site readableYes

How it was read: Every product listed in the brand's live catalogue is retrieved and its stated fibre composition read individually. From the product page, the store's own product data and its material labels. A fibre percentage is published only when 100% of the catalogue has been read. Items with no clothing textile (gift cards, packaging, jewellery, homeware) are excluded from the percentage rather than counted as a pass or a fail.

Why excluded: Items with no clothing textile to rate. Gift cards, packaging and returns kits, jewellery, homeware, toys, body care and checkout line-items. Removed from the fibre percentage rather than counted as a pass or a fail.
