These women's black Cinettica Pro Nix shorts are great for long bike rides. To use them, simply put them on like regular shorts before your cycling trip. When riding, you'll feel the comfort of the Italian chamois. For maintenance, wash them in cold water with mild detergent and hang them to dry. Avoid using bleach as it can damage the chamois. Also, don't iron them directly on the chamois area to keep its softness and functionality.
