The Woolpower 400 Long Johns are specially designed for use under thick outer clothing such as overalls or protective work clothing and the front opening makes it easier to go to the toilet outdoors. The extremely warm thermal underpants made from the Woolpower Ullfrotte fabric, which has been tried and tested for decades, create an almost unbeatable heat efficiency with little material. The internal loop structure binds air as a heat carrier and ensures rapid sweat wicking. The merino wool provides excellent warmth even in damp conditions and binds odors over the long term.
