Merino Wool Beanie Brown
- Warm even when damp — Merino wool blend keeps holding heat after a splash, a swim, or sea spray.
- Built to keep its shape — Nylon and acrylic content stop it from stretching out or pilling by spring.
- Soft, snug, all day — Ribbed knit fits close without squeezing. No tags, no scratch.

About Seashell
Seashell is built for what comes after the cold water — the walk back to the car, a warm flask in hand and laughs with friends after.
We make gear for cold-water swimmers, surfers, dippers, and anyone who's figured out that the best part of any session is the warmth that comes after.
Every product is designed in the UK and built from recycled or certified-natural fabrics. Reinforced where it matters, stripped of what isn't needed. Made to be used every day, not saved for special occasions.
If something fails in normal use within the first year, we replace it. If you change your mind in the first 30 days, we take it back.
£1 from every robe sale goes to The Captain Paul Watson Foundation, protecting the water our gear is made for.
Cold water. Shared laughter. A warm flask. Seashell is built for what comes after.

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.
30-day free returns on unworn items. Taken it out for a session and it's still not right? Get in touch anyway.
1-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.
Where are Seashell products made?
