How to use: Simply put on the jacket like you would any other. Zip it up when it starts to rain and enjoy your ride. The pro - fit cut means it'll stay close to your body and not flap around. When you don't need it, just fold it up and put it in the stuff sack. Attention: Although it's waterproof, don't expect it to be completely dry if you submerge it for a long time. Also, avoid sharp objects that could tear the fabric. Maintenance: After use, let it dry completely before storing. You can wash it with a mild detergent on a gentle cycle. Hang it to dry, and it'll be ready for your next adventure.
