Wool, a natural and renewable material, is renowned for its exceptional warmth and breathability. These characteristics have made wool a staple in creating high-quality thermal wear. Wool fibers have a unique structure that allows them to retain heat, providing natural insulation in cold conditions. This means our wool socks not only keep your feet warm but also manage moisture, preventing sweat build-up which can lead to discomfort and cold feet. Additionally, wool fibers are naturally resilient, giving our socks long-lasting durability. That's why these Canadian made wool socks are not just a purchase, they're an investment in comfort and warmth. These socks are crafted from a blend of 60% wool, 17% nylon, 10% acrylic, 10% polypropylene, and 3% spandex. They have a heat index of 3/4. Men's Avalanche Wool Socks
