The Xenon Race bib is made with lightweight, synthetic fabrics that are designed to pull moisture away from the skin and disperse it across the fabric's surface to enhance evaporation and keep you dry. Gore also built the Xenon to provide maximum support while you're in the riding position, and has oriented the seams away from potential irritation points for added comfort. Gore uses mesh for the upper portion for added breathability and provides reflective accents throughout to keep you visible in low light conditions. The Xenon Race includes Gore's Xenon Man chamois. The Xenon Man uses multiple densities of foam to guarantee support without cutting off circulation. The chamois features a blend of synthetic materials for optimal moisture management. Also, the chamois' stretchy quality allows it to better accommodate you while you're working away in the saddle, which eliminates chafing and ensures that you stay comfortable on long rides.
