Using the Race Face 1.5L Stealth Hip Bag is easy. First, adjust the single - sided stretch belt around your hip for a comfortable and secure fit. Put your water bottle in the neoprene holder. You can store snacks, tools, or other small items in the two main pockets. Keep your phone in the dedicated phone pocket. When it comes to maintenance, just wipe it with a damp cloth if it gets dirty. Avoid using harsh chemicals as they might damage the ripstop nylon or the 3D mesh backing. Make sure to close the waterproof zippers properly after each use to keep your stuff dry. Also, don't overload the bag to prevent it from stretching or breaking.
