2XU's Comp Trisuit delivers the performance typically offered by more expensive trisuits thanks to 2XU's quick drying SBR SKIN X featuring LYCRA fiber for compression and long lasting performance. SENSOR MESH X provides ventilation for all race conditions and the 2XU SBR Fleece provides the padding fo the bike while remaining discreet and comfortable for the run and swim. SBR SKIN X is engineered from powerful 70D elastane yarn with heightened compressive properties to support the wearer for greater endurance and higher power output. The 2XU SBR FLEECE uses a micro-filament polyester yarn with hydrophobic properties to keep you dry through all three disciplines.
