Hotwool long underpants 230g Unisex from Aclima are a pair of nice and warm long underpants in high quality. The underpants are made with Aclima Hotwool , which is made of terry wool, which is a mixture of wool, where the different fibers work together and make it possible to achieve thickness, high insulating ability and more wear-resistant than clothes made only of wool. Excellent for active outdoor use such as skiing and hunting. Designed in collaboration with the Norwegian Defense Forces. These long underpants are ideal as the inner layer. If you fluctuate between two sizes, take the number smaller, as they must fit tightly.
