2XU Light Speed

Designed according to research from RMIT University on ventilation and cooling to tackle the challenges of long-duration races, the sleeveless Light Speed Front Zip tri-suit offers superior muscle stabilization, heat dissipation technology, and unmatched aerodynamics. The ultimate cooling PWX VENT lower body provides support while enhancing airflow by nearly 200%, while the Swiss COLDBLACK® on the upper body reduces the absorption of thermal rays and offers UV protection to keep you at an optimal performance temperature.

Exceptional aerodynamics: The 3D mesh structure of premium Italian SBR VENT across the upper body provides outstanding aerodynamics and is ergonomically designed to fit your body like a second skin.

Muscle containment stamping (MCS): Accurate mapping of the quadriceps muscles for powerful support, dissipating load transfer on the knee joint while running.

Light and flexible support: Powerful and lightweight PWX fabric with 360-degree stretch circular knitting reduces muscle movement and prevents fatigue. The TMF® Light Speed Tri Chamois designed for Ironman distance features a dual-density chamois (a breathable 6 mm foam of density 90 combined with a super lightweight 3 mm foam of density 140) that utilizes Skyve technology - shaved and shaped foam - and the “Free-Edge” construction - all the outer edge of the pad is foam-free, making the stitches completely flat - for optimal support and comfort.

Essential storage: Easily accessible rear pockets provide adequate secure storage for your race day essentials.
