50% merino wool, 30% nylon, 20% acrylic
Care
Hand wash cold, or use a wool cycle at 30°C.
Reshape and dry flat — do not tumble dry.
Do not iron. No bleach or fabric softener.
Keeps your head warm from the first cold water dip to the coffee afterwards.
The merino wool blend holds heat even when damp. A splash, a swim or a bit of sea spray won't leave you cold. Soft, breathable and naturally odour resistant. Ideal for open water swimming, wild swimming and cold water outdoor activities.
The ribbed double layer knit gives a snug fit that sits close without squeezing. Nylon and acrylic content keep it from stretching out or pilling over time. No itch. No scratch. Just a merino wool beanie you'll reach for every day from autumn through to the last cold morning of spring.
Pairs perfectly with your Seashell changing robe. Subtle embroidered logo keeps it understated.

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.
