The Castelli Men's Superleggera Vest effortlessly travels in your rear jersey pocket, deploying when chilly breezes and passing showers threaten to leave you cold and wet. It fits closely to eliminate annoying flapping at higher speeds, yet it still allows room to layer properly in cooler seasons. Reflective hits along the front and back keep you visible to oncoming traffic in low-light situations.

Pertex Quantum is smartly placed along the body, blocking whipping winds from stealing precious body heat, as well as repelling light showers from dampening your upper body. Breathable mesh panels keep you cool on extended climbs and high-cadence efforts alike. Along the rear panels, the Stretch Torrent insert offers waterproof protection from oncoming weather without sacrificing its body-hugging stretch.
