How to use: Just zip up the full - length front zip when you're riding your bike. The internal storm flap will keep the wind and rain out. You can use the concealed zipped rear pocket to store small items like keys or energy bars. When not in use, simply pack it into the included stuff sack.
Things to note: Avoid sharp objects that could tear the fabric. Although it's waterproof, don't expose it to extremely heavy rain for a long time.
Maintenance tips: Wash it in cold water with mild detergent. Don't use bleach. Hang it to dry, and avoid direct sunlight and high - heat drying.
