Thermal Underwear

Having a set of thermal underwear can dramatically increase warmth and comfort. They are the best addition to your clothing layers when extra warmth without too much bulk is needed. Thermals are also great to sleep in to extend the warmth of your sleeping bag, or under a wetsuit making your canyon trip that little more enjoyable. It should be noted that cotton fibres are not an option as they are not thermally effective and do not retain heat when wet.

Thermal underwear is designed to be worn close to the body, covering your skin reducing heat loss and also absorbing any moisture from your body keeping your skin dry and warm.
