Description
Merino Wool Beanie
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.
