There are times when you just need a wind blocking vest. Think fast descending, cool mornings, or really any time that you need more protection than your jersey provides, but where a full on rain jacket just isn't practical. So, thanks to its ease of storage and legendary WindStopper fabric, the Gore Bike Wear Power AS Women's Vest will be there for you when you need it most. Gore's WindStopper is renowned for its supreme wind and weather blocking abilities, as well as its breathability. In other words, while it stops wind from cutting though, and blocks out most precip, the construction of the fabric lends itself to pulling moisture from the inside and transporting it to the surface where it can evaporate. There are stretch inserts, too, which work in conjunction with the contoured cut to keep the Power vest from pulling when you change positions. To make packing the Power vest easier, Gore included a stow pocket at the back. It compresses the vest to a size that will easily fit into your jersey pocket for quick access when the wind picks up. And to enhance your visibility to drivers, there are reflective accents throughout. The Gore Bike Wear Power AS Vest Women's is available in six sizes, from X Small to XX Large, and in the colors Black, Rich Red, and Waterfall Blue.
