When Castelli redesigned their wind vest and jacket, they understood we need a lightweight layer that protects from the wind, without making us catch the breeze like a sail. The Aria Vest combines a windproof front panel with a stretchy mesh back to keep the vest close to our body, helping us look every bit as classy with it on as when we're riding in a jersey alone. This is the ideal vest to bring along on a ride to stay warmer on the descent. We barely notice its 60g in our pocket while climbing and certainly appreciate the protection from the wind on the way back to the cafe.
