DoubleWool Longs is Aclima’s warmest long underwear with an outer layer in 100% merino wool. The underwear is made in a two-layer material and the fit is tight. The waist is lined in soft merino wool for best comfort against the skin. With DoubleWool, we have combined two of our best materials, WarmWool and WoolNet. The design takes advantage of the best from the material, with fantastic warmth and the best moisture transporting qualities. WoolNet is closest to the body, forming insulating air pockets and transporting moisture from the skin. The outer fabric in WarmWool contributes with insulation and help transport moisture from the body. DoubleWool is therefore an excellent choice, regardless if you’re going on an expedition, sitting quietly when hunting or simply being outside and doing what you enjoy the most in cold weather.
