Featuring a three micro-layer knit structure, Expedition Weight SUPER MERINO WOOL maintains a layer of air between an exterior and an interior fabric. The layer closest to your skin pulls moisture away, spreads it out and moves it to the outer layer for faster evaporation. This action allows the layer of air to maintain a more constant temperature. Most people enjoy Expedition Weight base layers when involved in "stop & go" activities in cold weather. Ideal uses: cold weather mountaineering, ice climbing, skiing and snowboarding. This is a western fit model and differs from Japanese sizes. Be sure to check the size chart before purchasing.

Base layers and the importance of layering

Hiking, trekking and climbing are all activities which involve swings in body temperature. When active, the body produces heat and perspires, and when finally emerging onto a ridge blasted by cold winds, the body temperature can drop to the point of shivering. Sudden rises or falls in body temperature can result in life-threatening issues such as hypothermia.
