The Thermawool Pant is made from 100% mercerized super soft merino wool jersey. The superfine merino wool fabric naturally manages moisture and temperature, insulating even when wet, and fights off odor with natural antimicrobial properties. No-itch wool is not only soft and warm, but also flame resistant and machine washable with a UPF rating of 50+ to protect your skin from harmful UV rays. Merino wool is an annually renewable resource. This breathable 180g fabric is constructed with flat seams, so that the Pant functions perfectly as a medium weight base layer. Thermawool Pant has an elastic waistband with plush back logo. Black.
