These Castelli Prima women's cycling shorts are easy to use. Just put them on like regular shorts before your cycling session. Make sure they fit snugly but not too tight. When cycling, you'll feel the comfort and support right away. As for care, it's best to wash them in cold water with mild detergent after each use. Avoid using fabric softeners as they can reduce the fabric's performance. Hang them to dry instead of using a dryer, which can damage the material. With proper care, these shorts will serve you well for many rides to come.
