The Sealskinz Bircham Waterproof All Weather Ankle Socks have been dsigned for a variety of temperatures. Stay comfortable and warm in the rain, snow and mud, standing in leaky waders, and through stream crossings.
Extremely Breathable:
Particularly noteworthy is the unmatched breathability of the hydrophilic waterproof membrane to release perspiration steam and warm air from inside the sock. This creates a high level of comfort for the wearer, even while performing strenuous and aerobic activities, while also preventing rain, mud, and sand from getting inside the sock.
Materials:
These 100% waterproof socks are constructed by bonding three layers together to make one highly waterproof and breathable sock:
Outer Layer: 62% Polycolon, 29% Nylon, 9% Elastane
Middle Layer: 100% Hydrophilic Membrane
Inner Layer: 36% Merino Wool, 36% Acrylic, 18% Polyester, 5% Nylon, 5% Elastane
Technology:
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, our socks stay waterproof under the toughest of conditions.
Sizing (EU):
Small: 36-38
Medium: 39-42

Please Note: The measurements above are your shoe size, so if you are a EU size 39 we recommend you would be a size M (Medium).
If you are at the top of a size such as a EU 42, we recommend you move up in size as these waterproof socks are thicker than normal socks.
