Nearly twice the warmth of foam, felt or pile, durable and compression resistant, Thinsulate can take a beating and still retain the little pockets of air, so important for keeping feet warm. Able to maintain warmth when wet - absorbing less than 1 of its weight in water - Thinsulate keeps feet warm even in damp conditions and after repeated washings, and dries easily.
