It's warm and windproof yet breathable thanks to the Castelli GORE-TEX INFINIUM™ windstopper fabric on the front and the membrane-free Nano Flex stretch woven back fabric. It's splash resistant for wet roads or changing conditions. It's light and packable, easily fitting in a jersey pocket with room to spare. It has three rear pockets of its own and a two-way YKK® Vislon zipper you can open it from the bottom to access gear in your jersey pockets.
