2XU Women's Light Speed React Short Sleeved Trisuit The 2XU Women's Light Speed React Short Sleeved Trisuit provides the ideal balance of pure speed and all-day comfort. Developed with insights from pro athletes at the highest level, this premium women's triathlon race suit features outstanding aerodynamics, exceptional heat-beating tech and 2XU's world-renowned muscle stabilisation, all combined to deliver the ultimate suit for Olympic and Ironman triathlons.  When it comes to drag-reducing aerodynamics, this is facilitated firstly via the SBR Silicone Ridges across arms and shoulders. These create 'rough' airflow that improves airflow efficiency to save watts as speeds increase. Then comes the SBR Channel spliced through the sides, again designed to improve aerodynamic performance while also enhancing breathability. Ergonomically shaped panels also give a smooth, wrinkle-free fit, eliminating flapping that could quickly burn off speed. This is a suit that's ruthlessly efficient through the air, gaining what might be called 'free speed'. Once you're up to race speed, you'll soon be warming up. Here, the combination of breathable, quick-wicking fabrics and the HeiQ Smart Temp technology works to keep you cooler and fresher when the heat is on. HeiQ senses body temperature increases and reacts by increasing moisture evaporation to increase cooling - push harder and stay cooler.  TMF® Light Speed Tri Chamois An Italian seat pad designed specifically for the demands of triathlon. Dual-density, dual-thickness foams provide perfect on-the-saddle support while the Skyve Technology sees layers shaped for optimal support where it's needed most and reduced bulk for a flexible run and swim. The 'Free Edge' construction ensures the edge of the pad sits perfectly flat, reducing the risk of chafing during each triathlon leg.
