Small enough to fit in your saddle pack and light enough that you'll forget it's there, the Pearl Izumi Women's ELITE Barrier Vest is the layer that will make the difference between a suffer-fest and a fun ride. While a downpour will render it ineffective, it will resist light precipitation and prevent wind from stealing your core warmth. It's constructed with ELITE Barrier fabric, which stands up to the elements without turning your torso into a portable sauna. Direct-Vent panels use mesh to further enhance ventilation, ensuring that as you sweat the vapor has an escape route. A slim silhouette serves two purposes----it keeps the fabric out of your way while you pedal your way to a new PR, and it has a flattering look when you roll up to the local cafe for a post-ride latte. A drawcord at the waist adjusts with a single hand, so there's no need to stop riding to protect yourself from gusts as the wind starts to pick up.
