Using the Torvol Quad Pitstop Backpack Pro ELITE is a breeze. First, unzip the main compartment and start loading your FPV gear. The extra strap can be used to secure any additional items on the outside. When you're ready to go, put the backpack on and adjust the straps for a comfortable fit. Make sure your back is well - supported thanks to the rider - centric design. As for maintenance, if it gets dirty, simply wipe it down with a damp cloth. Avoid using harsh chemicals as they might damage the UV protection and water - repellent features. Store it in a cool, dry place when not in use to keep it in good condition. Be careful not to overload the backpack beyond its capacity to prevent any damage to the zippers or the structure of the bag.
