Giro M Chrono Long Sleeve Base Layer

The key to temperature control in cold weather is sweat management. The Chrono LS Base Layer with our proprietary Wikpro™ material keeps you warm, dry and comfortable in the coldest conditions. Wikpro™ is a proprietary blend of polyester and nylon that improves moisture transport while remaining comfortable to wear. This is the same fabric from our popular Chrono SL Base Layer undershirt, but in a heavier quality for extra insulation. This first layer is the basis for a comfortable ride in cool temperatures.
