Smart design offers dual-weight Merino in one ultra-performance base layer. Body mapping construction utilizes both 250 & 190 gram weight Merino Wool panels for the perfect blend of breathability, warmth, and cooling over a wide range of temperatures. 250 gram Merino is used in the core areas (front, chest, and arms) while the lighter 190 gram merino is used under-arms and back panels to cool your heat zones and wick moisture.
Worn by itself, this super comfortable and light-weight top wicks away moisture to help keep your cool in the heat of the moment; or layer it under and outer piece to hold a warm layer of air near the skin as the perfect low-profile performance insulation. Comfortable next to the skin, natural odor resistant qualities and moisture wicking performance to always keep you in your element.
