This backpack is useful, but very small. Im not sure that it will meet my needs. I like the security of the zippers and RFID, and the price point was good. The shape is narrow at the opening and wider at the bottom. Im not sure if itll hold much more than my rolled up raincoat. For me, I think its a bit too small - more like a purse than a backpack. Material is water-resistant, very plain style.
