The Ultimate Weapon for Long-Course Racing

Leveraging insights from elite ambassador testing and aerodynamic research drawn from Tour de France skinsuits, the 2XU Light Speed React Sleeved Trisuit is engineered to be the ultimate weapon for long-course racing. Built for Ironman-distance performance, this trisuit delivers exceptional aerodynamics, intelligent cooling and unrivalled muscle stabilisation to help you maintain speed, efficiency and comfort when it matters most.

Why Choose the Light Speed React Sleeved Trisuit?

Exceptional aerodynamics

SBR SILICONE RIDGES across the arms and shoulders, combined with SBR CHANNEL fabric spliced through the sides and centre back nutrition pocket, help roughen airflow to reduce drag. Clean-cut finishes further minimise loose fabric for a streamlined, race-ready profile.

Ultimate cooling

SBR SKIN LITE stretch interlock actively wicks sweat away from the upper body, while HeiQ Smart Temp technology responds to rising body temperature by increasing evaporation—keeping you cooler for optimal long-course performance.

Powerful & lightweight support

A 10-inch compression short constructed from lightweight PWX fabric reduces muscle movement, improves stability and helps delay fatigue across extended race durations.

TMF® Light Speed Tri Chamois

Designed specifically for Ironman-distance racing, this advanced chamois delivers premium comfort and support without excess bulk.

Essential race-day storage

A large centre back aero pocket with dual side access, plus additional internal nutrition pockets and an easy-access ice pocket at the back neck, provide secure, bounce-free storage for fuel and essentials in hot conditions.
