When your next adventure calls for a balance of warmth, breathability, and waterproof protection, Sealskinz Cold Weather Waterproof Mid Calf Socks fit the bill. 3-layer construction uses a 90% nylon/10% elastane shell for durability, a hydrophilic membrane for waterproof performance, and a 35% Merino wool/35% acrylic/23% polyester/3.5% elastane/3.5% nylon lining for next-to-skin comfort and warmth. The Merino wool wicks moisture away from your feet and regulates temperatures, keeping them dry and comfortable from the inside.
