Our well - known waterproof socks are upgraded to handle the cold. With their knee - length design, they'll keep you dry and allow you to keep going. Wet and cold feet are no joy and can cause a host of outdoor problems like numbness, blisters, and frostbite. These socks are your go - to for staying warm and dry in rain, snow, or mud. The knee - length offers extra protection, making them the ultimate choice to make harsh weather a non - issue.
These cold - weather socks feature a three - layer bonded construction. The 100% waterproof hydrophilic membrane is combined with a top - notch Merino wool interior. The Merino wool not only provides warmth but also wicks away sweat. The exterior is a durable nylon blend with 4 - way stretch for a great fit and easy wear. Designed with warmth in mind, these socks use the finest Merino wool and an added terry - loop knitting layer. This loop knitting traps heat in the air pockets, keeping you warm even in the coldest situations.
Whether you're crossing frigid streams, hiking in the rain, commuting on a chilly day, hunting in wet and cold conditions, or working outside in cold and wet weather, our Waterproof Cold Weather Knee Length Socks will keep you dry, warm, and protected.
**Technology**: We were the first to use a unique hydrophilic membrane. It's 100% waterproof and pulls moisture away from your skin at the molecular level, keeping you dry and cool simultaneously. With a Hydrostatic Head of >20,000mm, these socks stay waterproof under the toughest conditions.
**Materials**: Our 100% waterproof socks are made by bonding three high - quality layers together to create a highly waterproof and breathable sock:
- Outer Layer: 90% Nylon, 10% Elastane
- Middle Layer: 100% Hydrophilic Membrane
- Inner Layer: 35% Merino Wool, 35% Acrylic, 23% Polyester, 3.5% Nylon, 3.5% Elastane
