Carhartt Men's Arctic Wool Heavyweight Sock:
The Carhartt engineering that went into these socks demanded the perfect blend of materials. Carhartt found it with a combination of wool, nylon, polyester, acrylic and Lycra. Wool is a great natural fabric. The high wool content gives you excellent thermal regulation, vapor transport, and odor resistance. Each of the materials provides a feature that makes these Carhartt boot socks the perfect beginning of your expedition.
They’re the perfect weight for comfort and warmth. In addition, this footwear is equipped with reinforcements at the heels and toes which are designed to reduce abrasion and add to the life of your socks. The spandex and a non-terry vent reduce the bulk. That means they fit inside your boots better and won’t cramp your style.
