Sumarpo makes triathlon wetsuits and says the brand emerged from a small UK design studio in 2008. The brand says its wetsuits use Yamamoto limestone neoprene, water based adhesive and recyclable lining fabrics.

It says its recycled lining fabrics follow the Oeko-Tex label. It pledges 1% of annual sales to environmental causes through 1% for the Planet.

Is Sumarpo a sustainable clothing brand? See the real fibre breakdown, plant, animal or synthetic, before you buy.

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.

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.
