The men's Extra Warm Merino Longpants, made from 100% finest 190s merino wool yarn, offer optimal heat and moisture regulation. A special knitting process ensures an ultra-soft feel and excellent stretchability. Merino wool is thermoregulating, odorless, easy-care and crease-free. The curled fibers form air chambers that trap body heat. This functional underwear always keeps the body dry and warm, even in cool temperatures. The longpants offer maximum comfort and natural heat protection, ideal for demanding outdoor activities in cold environments.
