Using this Midloader Bikepacking Frame Bag is a breeze. First, find the empty space in your bike frame where you want to mount the bag. Then, use the hook - and - loop fasteners to attach it firmly. When you're packing, put your heaviest items inside as the bag is designed to handle the weight. To access your gear, simply unzip one of the two water - resistant zippered openings on either side. As for maintenance, keep it dry after use. If it gets dirty, you can gently wipe it with a damp cloth. Avoid using harsh chemicals as they might damage the water - resistant and durable materials. Also, when not in use, store it in a cool and dry place.
