How to use: Just put on the jacket like you would any other outerwear. It's easy to zip up with the YKK® Vislon® zipper. Use the rear pockets to store small items like your phone, keys, or energy bars. When riding in low - light conditions, the extra reflectivity will help keep you visible. Notice: Avoid sharp objects that could tear the fabric. Don't overstuff the rear pockets as it might affect the fit and comfort. Maintenance: You can machine - wash the jacket on a gentle cycle with mild detergent. Hang it to dry to maintain its shape. Don't use bleach or harsh chemicals as they can damage the fabric and the reflective elements.
