The very light and easily packable vest offers protection from wind, road spray and light rain. The two-way stretch polyamide fabric has a fluorocarbon-free DWR (durable water repellent) finish to keep road spray and light showers away. The inside of the collar and back are made from a very lightweight mesh fabric for comfort and functionality, providing exceptional ventilation. A full-length two-way YKK zipper makes it easy to control ventilation and access underlying jersey pockets while riding.
