Rab Hot Socks

Jump to: Our Verdict / Features / Specifications

A super lightweight and packable sock updated with PrimaLoft Silver synthetic insulation and recycled fabrics. Ideal for use on expeditions, hut tours and backpacking to warm up your feet and lock in the heat on chilly evenings.

Rab says

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.

Our Verdict

Rab’s Hot Socks are perfectly designed to be kept in your backpack and then put on when you camp for the evening or arrive in your hut for the night.

They provide instant warmth when you put them on so they are perfect after a cold day walking.

The ankle opening is rather narrow so it takes a bit of effort to put them on. The sole is also quite slippery on tent floors and solid wood hut floors so I would be very careful when moving about with them on.
