Using this hip pack is a breeze. Just adjust the strap to your preferred length between 8 inches and 36 inches and put on the pack around your hips. Fill it with your essential items like keys, phone, or a small wallet. When you're done using it, simply fold it up and tuck it into its own pocket for easy storage. As for maintenance, you can gently hand - wash it with mild detergent when it gets dirty. Avoid using harsh chemicals or machine - washing to keep the recycled materials in good condition. Also, make sure not to overload the pack beyond its 1 - liter capacity to prevent any damage to the straps or the fabric.
