The combination of ultra-soft merino wool and technical fibers in this ski base layer creates a soft, durable, breathable, and naturally odor-resistant fabric, while underarm panels ensure optimal movement without any ride-up. This long sleeve thermal shirt has smooth flatlock seams, so that you don’t have to worry about any chafing when you’re on your winter adventures.
