Lightweight and breathable. Handcrafted in the Sealskinz factory in Norfolk. *In very rare cases, close bond between sock cuff and skin may lead to rubbing. Technology Sealskinz three-layer AQUASEALZ composition sees a 100% waterproof hydrophilic membrane enmeshed between a premium merino wool interior and an extra-durable nylon exterior. Outer – Durable nylon exterior, with 4-way stretch for an optimal fit. Mid-Section – Aquasealz waterproof membrane releases body-generated heat and moisture, while denying intrusion of external elements. Interior – Premium merino wool and acrylic blend for softness, sweat-wicking and odour resistance. Hydrostop Hydrostop is an elastic taping around the inside cuff of the sock. This extra barrier reduces the risk of water dripping down the leg into the sock. Activities Our community is made up of athletes and adventurers. The Briston is a cousin of the Raynham.
