Designed with a slight compression effect to provide a tight fit that moves with your body while performing. This super light weight fabric contours perfectly to the body and guarantees a perfect ergonomic fit and racing performance. Advanced fibers and fabric construction block cold air or moisture coming in, but stay highly breathable. Silicone strips in the hem prevent the jersey from riding up. Carbon fibers shield the body from absorbing static energy and UV rays. The structure of the fabric accelerates evaporation of moisture keeping the skin dry and cool. It is antibacterial and inhibits the development of odor causing bacteria.
