Standout, get noticed, and stay warm in 2XU's HYOPTIK Thermal Tights that is ideal for your cold-weather adventures. The PWX FLEX fabric wraps your muscles for added support, reduced vibrations, and better protection from damage and fatigue. This anti-bacterial tight is rated with UPF 50+ that protects your skin from harmful UV rays. While a graduated compression construction fuses with soft brushed thermal inner layer to provide improved blood circulation and extra warmth in cold climate, flatlock seams reduce chafing, and high filament yarns ensure dryness and moisture-wicking properties. Thanks to the HYOPTIK reflective logos, this travel tight keeps you visible when you're out for a run in low light conditions.
