How to use: Just put on the vest like any other top. You can open the two - way zipper from the bottom to reach the stuff in your jersey pockets. For storage, it's super easy to pack it into a pocket when you don't need it. Attention: Although it's splash - resistant, don't expose it to heavy rain for a long time. Avoid sharp objects that might tear the fabric. Maintenance: Wash it according to the label instructions. Usually, a gentle cycle with mild detergent is enough. Hang it to dry, and it'll be ready for your next cycling adventure.
