Using your Basil rain cover is a breeze. First, open the cover and place it horizontally over your laptop bag, messenger bag, or bicycle shoulder bag. Attach it easily using the Hook - On system at the back. Adjust the cover with the roll - top closure and click it securely on the sides. When the rain stops, simply remove the cover. To keep it in good condition, avoid sharp objects that could tear the 600D polyester material. If it gets dirty, you can gently wipe it with a damp cloth. When not in use, pack it into the included storage pouch. This way, your rain cover will be ready for the next rainy day.
