Sealskinz pioneered the use of a unique hydrophilic membrane that's 100% waterproof yet pulls moisture away from your skin at the molecular level -- keeping you dry and cool all at the same time. And with a Hydrostatic Head of >20,000mm, the socks stay waterproof under the toughest of conditions.
In serious downpours water can bead up on bare legs and calves and egress into the socks through the top. So Sealskinz invented Hydrostop™, a silicone-like (although it is silicone-free) elastic taping around the inside cuff of the sock. This added protection reduces the chances of water dripping down your leg into your sock. Problem solved.
The 100% waterproof socks are constructed using premium materials and by bonding three layers together to make one highly waterproof and breathable sock:
• Outer Layer - 90% Nylon, 10% Elastane
• Middle Layer - 100% Hydrophilic Membrane
• Inner Layer - 35% Merino Wool, 35% Acrylic, 22% Polyester, 3.5% Nylon, 3.5% Elastane, 1% TPU
This is the type of sock you can throw in the wash along with the rest of your gear. No need to line dry or wash with special detergents. Since the membrane is a solid barrier, you'll never need to re-waterproof.
