Features
3 of 5
Feature 1
Sumarpo makes triathlon wetsuits from limestone-based Yamamoto neoprene, a synthetic rubber rather than a natural plant fibre, bonded with a water-based, benzene-free glue. Its linings are recycled and meet OEKO-TEX standards, with a Slip Skin lining made from recycled plastic bottles, and it runs a separate Yulex natural-rubber swimsuit line.
Feature 2
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.
Feature 3
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.

Supply-chain summary
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.

How it was read
Throne identifies the eligible textile products in Sumarpo'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.
Coverage method pre dash fix
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.
