Designed based on research from RMIT University on ventilation and cooling to tackle the challenges of long-distance races, the short-sleeve triathlon Light Speed provides superior muscle stabilization, heat evacuation technology, and unparalleled aerodynamics. The ULTIMATE COOLING PWX VENT lower body offers support while enhancing airflow by nearly 200%, while the Swiss COLDBLACK® on the upper body reduces thermal ray absorption and provides UV protection to keep you at an optimal performance temperature. EXCEPTIONAL AERODYNAMICS: The 3D mesh structure of the premium Italian SBR VENT across the upper body offers exceptional aerodynamics and is ergonomically designed to fit your body like a second skin. MUSCLE CONTAINMENT STAMPING (MCS): Precise mapping of the quadriceps muscles for powerful support, dissipating load transfer on the knee joint while running. LIGHTWEIGHT AND FLEXIBLE SUPPORT: Powerful and lightweight PWX fabric with 360-degree stretch circular knitting reduces muscle movement and prevents fatigue. TMF® LIGHT SPEED TRI CHAMOIS: Designed for Ironman distances, the double-layer chamois (a 6 mm density 90 breathable foam combined with a super-light 3 mm density 140 foam) utilizes Skyve technology - shaved and shaped foam - and the 'Free-Edge' construction - the entire outer edge of the pad is foam-free, making the seams completely flat - for optimal support and comfort. ESSENTIAL STORAGE: Easily accessible rear pockets provide secure storage for your race day essentials.
