Castelli Fly Vest

The Castelli Fly Vest insulates body heat and blocks wind in an extraordinarily lightweight cycling vest. Castelli’s new FLY Fabric Technologies creates a performance piece of gear that protects a bike racer from chilly wind and rain in an aero vest that feels nearly weightless. The sides and back are made with a stretchy material that provides a perfect fit as a rider shifts his position on the bike. The CLIMA SL insulation layer and FLY SL shell keep you warm and shield from wind with 100% recycled fibers that are amazingly soft and lightweight. Treated with a water-repellent finish, the outer shell keeps you dry. The GORE-TEX INFINIUM™ WINDSTOPPER® inner lining keeps you warm in moderately chilly weather while providing enough breathability; body heat and sweat are pulled away from your body on high intensity rides and races. Stretchy and lightweight fabric on back provide a close comfortable fit. The low collar stays close to skin to keep out wind. The collar is also soft and very comfortable. When you need extra ventilation, the YKK® Vislon® zipper slides open easily for extra ventilation. For long distance rides and races, three back pockets provide plenty of storage space and reflective details increase visibility.
