Women's partly waterproof windbreaker: The Castelli SQUADRA STRETCH W is a lightweight windbreaker that should always be close by. Thanks to its light weight and compactness, it fits comfortably in the back pocket of your jersey. It will protect you from the wind and, in an emergency, from a light summer shower. It is cut tighter to the body and fits perfectly thanks to its side elastic panels, so it does not inflate unnecessarily in the wind or downhill like other wind jackets. Distinct reflective elements ensure your safety on the road.
