Comfortable muscle support & durability come together in a perfect balance when it comes to the Active Tri Singlet from 2XU. The SBR Skin Lite fabric used here is a blend of high-dernier nylon & super stretchy 50D elastane which keeps it close to the torso without ever feeling tight & still allow for a highly impressive range of movement. Breathable ventilation is provided by Sensor Mesh X panels that keep you cool when you’re really up against it, & also wicks sweat away from the body to dry quickly at the surface before you even notice it building up. Finally, an intelligent rear pocket system keeps essential race-day items within easy reach at all times. All in all, the 2XU Active Tri Singlet is the full package for both racing & training.
