FAQs
What materials do you use, and which products are recycled?
Our waterproof hero pieces are built from 100% recycled polyester and nylon, certified by the Global Recycle Standard (GRS) and OEKO-TEX Standard 100. Third-party tested, not just marketing speak.
Our knitwear uses a 50% merino, 30% nylon, 20% acrylic blend — chosen for warmth, durability, and shape retention rather than recycled content. Our socks use a similar performance blend.
Each product uses the right material for the job — we don't tell sustainability stories we can't back up.
Where does the £1 to marine conservation go?
The Captain Paul Watson Foundation works to protect ocean wildlife and challenge illegal fishing worldwide.
£1 from every robe sale. No fine print.
