Ale Vests add minimal weight to the cyclist and provide the protection so necessary on windy, chilly days. The vests are constructed with compressive fabrics so they have a smooth, aerodynamic fit. Highly breathable fabrics are combined with carbon which results in vests that protect but don't restrict. Ale vests are easy to open and close even while riding the bike. When the wind slows and the temperature rises, these vests are compact enough to fold into the back pocket of a jersey and will not even be noticed.
