Giro Chrono Base Layer Sleeveless Men's

A good base layer will only make your rides better, and Giro's Chrono Base Layer is a classic example of what ultralight fabric construction in a contoured silhouette can do. Constructed with Wikpro, a light synthetic blend, the Chrono is designed to closely hug your body so that it can immediately pull moisture away from your skin, transferring it to your jersey so that it can evaporate as quickly as possible.
