The original, military-trusted sock, reinforced with Hydrostop™. A men’s and women’s waterproof sock, the Briston thrives in multiple environments. Hydrostop™ prevents water from dripping down the leg into the sock. Lightweight and breathable. Please note: In very rare cases, a close bond between the sock cuff and skin may lead to rubbing.

• Sealskinz three-layer AQUASEALZ™ composition sees a 100% waterproof hydrophilic membrane enmeshed between a premium merino wool interior and an extra-durable nylon exterior.
• 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.
• Outer: (90% Nylon, 10% Elastane) Durable nylon exterior, with 4-way stretch for an optimal fit.
• Mid-Section: (Aquasealz®) Aquasealz™ waterproof membrane releases body-generated heat and moisture, while denying intrusion of external elements.
• Interior: (36% Merino Wool, 36% Acrylic, 18% Polyester, 5% Elastane, 4% Nylon, 1% TPU) Premium merino wool and acrylic blend for softness, sweat-wicking and odour resistance.
