The Women's Summit Wind Jacket is your lightweight layer of certainty when the weather shifts without warning. Designed to pack down to the size of a baseball and stash directly on your bike, it's always ready to deploy when cold wind, unexpected sprinkles, or fast descents demand protection. The wind-blocking ripstop fabric is treated with PFAS-free PI Dry® for durable water repellency, while a two-way YKK® front zipper lets you vent from the bottom or access rear pockets without slowing down. A hood adds warmth when you're off the bike, and BioViz® reflectivity ensures visibility when daylight fades. It's the layer you forget you packed—until you're glad you did.
