Keeps your feet warm long after your boots come off wet.
The 48% merino wool blend holds heat even when damp. Ideal for the walk back from the water or a cold morning outdoors. Naturally warm, breathable and odour resistant. Perfect for open water swimming, hiking, walking and cold weather outdoor activities.
A touch of spandex keeps them holding their shape with no sagging or slipping inside boots. Reinforced nylon at the heel and toe means they're built for hundreds of wears, not a single season. Cushioned and snug without the bulk.

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.
What's your return policy and guarantee?
Two things, so you're covered either way.
60-day free returns on unworn items. Taken it out for a session and it's still not right? Get in touch anyway.
3-year performance guarantee on anything that fails in normal use — stitching, zips, hardware, fabric defects. Accidental damage isn't covered, but genuine manufacturing faults are on us.
