Sealskinz Warm Weather Mid Sock

We 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, our socks stay waterproof under the toughest of conditions.

Our 100% waterproof socks are constructed using premium materials and by bonding three layers together to make one highly waterproof and breathable sock:

• Outer Layer - 94% Nylon, 6% Elastane
• Middle Layer - 100% Hydrophilic Membrane
• Inner Layer - 75% Bamboo Rayon, 23% Nylon, 2% Elastane
