Bison Thor.1 Lycra Men's Undersuit

Our 100% Lycra Thor.1 undersuits are comparable to those costing twice as much. The material is antimicrobial and wicks moisture while breathing in hot weather, yet keeps you warm in cooler weather. Red flat-lock seams provide comfortable, durable and handsome construction. Two zippers in front allow for that pre-race potty break without having to undress completely, and stirrups on arm and leg sleeves make ingress and egress of your suit easier than ever.
