Utilizing 2XU's powerful 70D/CK fabric for increased power and durability, this garment arms the athlete with greater power output through less muscle oscillation plus increased blood flow to reduce lactic acid build-up. ICE X fabric is engineered for endurance events like no other. Xylitol is embedded in the fabric yarn to draw heat from the body and IR blocking inhibits penetration of infrared rays to lower skin temperature by up to 5.4 degrees farenheit. This garment will excel in all conditions, especially keeping you cool when it's hot outside. The Elite LD Chamois is a multi-layered, fusion welded chamois featuring revolutionary perforation technology for ventilation plus impressive quick drying capability for greater comfort on the bike.
