A good thermal layer is the key to happy snowboarding. WearColour have designed some awesome thermals that you wear directly next to your skin to keep you warm and dry. They are made out of a soft ans stretchy Polyester called SwiftDry. This keeps warmth in but wicks moisture away. The thermals are sewn with flat seams to be comfortable against your body and they are "chafe-free". They come in different designs to suit individuals and fits perfectly from the first wear.
