DoubleWool Longs are Aclima's warmest long johns, with an outer layer in 100% merino wool and two layers of fabric in total. The fit is close-fitting, and the elastic waistband has soft merino wool on the inside against the skin. The garment is reinforced with rib-knit fabric on the inside of the knees and thighs for improved durability and freedom of movement. At the top on the left side you will find an embroidered logo.

Here two of Aclima's best materials are combined: WoolNet and WarmWool. Next to the body sits WoolNet, which creates insulating air pockets between the two layers and transports moisture out to the next layer. On top of the wool mesh lies WarmWool, which insulates further and moves moisture even further away from the body. Together these materials provide both excellent insulation and very effective moisture transport.

Aclima recommends DoubleWool Longs as a base and mid layer, whether you are heading on an expedition, sitting still on a hunt, or out in harsh weather.
