Using this Klein Tools tool backpack is a piece of cake. First, you can put your safety glasses in the hard, molded front pocket to keep them safe. Then, use the front zipper pocket for small parts like screws and nuts. For long screwdrivers, the taller bag and interior pockets are there for you. When you're ready to carry it, the extra - padded shoulder straps and handles make it easy on your shoulders. As for maintenance, if it gets dirty, you can wipe it down with a damp cloth. Since it's water - resistant, a little rain won't harm it, but try not to submerge it in water for a long time. Also, avoid overloading it to prevent any damage to the pockets or the structure of the bag.
