The hot socks are ultra-warm and packable, perfect for basecamp on cold expeditions or as refuge for cold toes on an alpine bivi. Ideal inside a tent or for hut use, the Hot Socks are insulated with PrimaLoft® Silver, a synthetic material made from 100% post-consumer recycled material. With thousands of heat trapping air pockets this synthetic insulation is durable and water resistant.

The Hot Socks are wrapped snugly in a lightweight 20D recycled fabric with minimal seams to reduce heat loss, and have a sturdy 900D nylon sole which further insulates your feet from the ground. They reach just above the ankle with a comfortable stretch cuff and pack down easily into their stuff sack for storage in your pack.
