When the weather is brisk but the yetis haven't quite come out of hibernation, you'll want a cycling jacket that keeps the wind at bay without overheating your core. The Gore Bike Wear Women's Power AS Jacket is a must have for your shoulder season arsenal. The Power AS Jacket was constructed from Windstopper, which is designed specifically to shield you from wind. While it's not an insulating membrane, by minimizing cold air from flowing over your skin, warm body heat is kept close to your core. This keeps you from getting chilled. The jacket features stretch panels for optimal freedom of movement, and it's lightweight enough to take off and slip into your jersey pocket if the wind dies down and the sun starts to shine. A full length zipper is housed in a zipper port, and a semi lock slider prevents it from slipping down while you ride. A stow pocket holds your riding essentials, and, for low light visibility, reflective prints and piping have been added to the back and sleeves. The Gore Bike Wear Power AS Jacket Women's is available in sizes X Small through XX Large and in three colors: Waterfall Blue, Rich Red, and Black.
