The men's Oasis leggings with fly make cool weather sports better, day after day. Crafted from ultra soft, breathable 200gm Merino jersey, they provide enough warmth under a pant for really cold days in winter sports, but breathe well enough for morning runs in the fall or hiking high in the mountains. Flat lock seams and a brushed waistband eliminate chaffing, and because Merino resists odor naturally, they are ideal for multi-day adventures.
