2XU - Light Speed React Trisuit - Women's - Black/White - 2026

THE ULTIMATE WEAPON FOR LONG-COURSE RACING

Elite-Level Trisuit Engineered for Long Distance Triathlon Performance

The 2XU Light Speed React Trisuit is built for athletes racing in the most demanding long-course conditions. Designed using aerodynamic research from Tour de France–level skinsuits and tested by elite ambassadors, this trisuit delivers exceptional speed, advanced cooling and powerful muscle support. Lightweight, race-proven and uncompromising, it’s engineered to perform when the heat is on and the distance is long.

Why Choose the Light Speed React?

Exceptional aerodynamics

SBR CHANNEL fabric spliced through the sides and centre back pocket helps disturb airflow to reduce drag, while clean-cut finishes minimise loose fabric for a streamlined race fit on the bike.

Advanced thermoregulation

SBR SKIN LITE stretch interlock actively wicks sweat away, while HeiQ Smart Temp technology reacts to rising body temperature to boost evaporation and keep you cooler in hot, humid conditions.

Second-skin compression support

A 10-inch compression short made from lightweight PWX fabric stabilises muscles, improves circulation and reduces fatigue over long distances.

Quick-drying performance fabrics

Hydrophobic, fast-drying materials ensure comfort straight out of the swim and throughout the bike and run.

Race-optimised storage

A large centre back aero pocket with dual side access, plus internal nutrition pockets and an easy-access ice pocket at the back neck, provide secure storage without bounce.

Who Is This Trisuit Made For?

The 2XU Light Speed React Trisuit is designed for performance-driven long-course triathletes chasing peak results. Ideal for Ironman-distance racing and hot-weather events, it’s made for athletes who demand maximum speed, cooling and endurance support from their race-day kit.
