The men's BLACKSHEEP 2.0 tight Fly leggings by SAXX Underwear are snug and warm, an ideal base layer for colder temperatures. Move in comfort in the merino wool blend that stretches. All the SAXX hallmarks are here - the friction-free BallPark Pouch support, a Three-D 9-panel fit construction, and non-chafing Flat-Out seams. The leggings have an anti-microbial performance which combats odour. The jacquard waistband is built not to roll.
