Using the Hopper frame bag is a breeze. To access your items, simply use one hand to open the magnetic closure. You can run your hydration tubes or battery wires through the main panel opening for easy access while riding. For installation, adjust the attachment points on the daisy chain along the top tube to fit your bike. When packing, you can expand or compress the bag according to your bike's profile. As for maintenance, keep it clean by wiping it down with a damp cloth after each use. Avoid exposing it to sharp objects to prevent damage to the RevX - PAC panels. If it gets wet, let it dry completely before storing it. That way, your Hopper bag will serve you well for a long time.
