If you're prepping for an epic day on the mountain or crag, layer on the Marmot Polartec Baselayer Men's Tights. Constructed with midweight fabric for extra warmth under your gear, their flatlock seams keep you comfortable during long days of wear. A horizontal flip-out fly offers easy access, while the gusseted crotch on this pair of athletic tights increases mobility. Unlike other men's leggings or thermal tights, this pair offers built-in UPF 50 that provides extra protection from the sun.
