Using this top tube frame pack is a breeze. First, locate the top tube and seat tube of your bike. Then, use the strong Velcro straps to attach the pack securely to these tubes. Make sure it's firmly fixed so it doesn't move around while you're riding. When packing, you can put heavy items like tent poles, tools, and food inside. This helps in keeping the center of gravity low for better riding. Since the bag is waterproof, you don't have to worry if it gets wet in a river or rain. However, avoid using sharp objects near the bag as they might damage the material or the zipper. To maintain it, just wipe it clean with a damp cloth after each use. If there are any stubborn stains, you can use a mild soap. Keep it stored in a dry place when not in use to ensure its longevity.
