Just as the pros do, you know that layering isn't just for bitingly cold rides, it's actually a strategic way to actively manage your core temperature and curb excessive sweating when it's warm outside. And just as the pros on your favorite team do, you wear the Castelli Team Sky Pro Mesh Sleeveless Jersey to effortlessly regulate your body temperature and manage moisture, regardless if you're riding in frigid conditions with a thermal long-sleeve or in sweltering heat with your most breathable jersey. As usual, Castelli's 3D mesh fabric remains cool-wearing and comfortable underneath your favorite jerseys and actively pulls moisture off your body to keep you cooler in summer and warmer in chilly transitional seasons, such as late-autumn and spring. It sits tightly against your skin, which further aides in its ability to pull sweat off your body and features a hem that lies flat underneath your shorts. Additionally, it's finished with a Team Sky logo for displaying team allegiance when you unzip your jersey to cool down.
