Buy layering clothing: whether it is a thermal baselayer or a fleece the main goal is to trap air to insulate the body. This will keep you warm in the coldest of conditions but also by being breathable and wicking away any sweat will keep you the most comfortable. We have a great range of thermal clothing from Mons Royale, Salomon, Helly Hansen and Trekmates. These base layers should be worn against the skin and be relatively tight fitting but not restrictive. These will 'wick' the moisture from your skin to the next layer; keeping you dry and warm!
