Designed for very cold and moist conditions, UpHill Sport “Arctic” Tactical H5 Socks are high calf length socks to keep legs and feet warm and dry. These extra thick, multi-layer thermal socks are merino wool rich, for the fibre’s natural insulating, breathable and moisture handling abilities. All Uphill Sport merino wool products are mulesing free, to prevent cruelty to flocks. These Finnish designed and manufactured socks are soft inside, terry loop lined for cushioning and heat retention, and incorporating extra Lycra that improves support throughout, and contributes to comfort by keeping the sock in place and wrinkle free. The use of seamless toes protects against unwanted rubbing and blisters.
