Powerful compression and stand out style coalesce within the 2XU Hyoptik Compression Tights. Engineered with graduated compression for enhanced bloodflow, these full length tights protect key leg muscles from soreness and fatigue resulting from high endurance workouts. PWX Flex fabric strategically supports your abductor, glute, quad, hamstring, and calf muscles. Plus, you'll find the highly reflective Hyoptik logos radically boost visibility during low light conditions. The tights' UPF 50 rating ensures proper protection from harmful UV rays, while its antimicrobial treatment prevents the growth of odor causing microbes. Its high filament yarns facilitate the evaporation of built up perspiration for a cool, dry feel. Other key features include a wide flat waistband with drawstring closure, as well as flatlock seams for a smooth on skin feel.
