Hot racing.Giro's top-of-the-line, flagship men's road jersey introduces itself this year as the short-sleeve Chrono Pro Jersey, and it's eager to become one of your staple pieces of kit with uncompromising fit and functionality. The Chrono Pro relies on three different types of closely-related fabrics in its construction. The stretchy polyester and elastane main body is complemented by sleeves in a nylon blend and breathable mesh side panels. Each fabric panel is adept at wicking moisture away as you sweat and manages to feel light against your skin, recommending the jersey for hot summer days.If you're looking for a jersey that won't highlight the aftermath of an indulgent off-season filled with family and food, the Chrono isn't it. We wouldn't worry too much, as once you return to race weight, the Chrono's tapered neck, longer arms, and body-hugging fit will be ideal, following your body movements without bunching or stretching. Giro doesn't omit expected details like three rear pockets and a full-length zipper, and it adds reflective accenting to help you stay visible to motorists out on the road at all hours of the day.
