With rigid materials used on the back, items in the bag only project towards the inside, which avoids distortion and therefore enhances wear resistance. Rigid materials also protect objects inserted by reducing damage caused by shock. The extended velcro on the back prevents falling off when you put objects into the bag or pull them out. It can be taken down only when the Velcro on the top is open.
