My child used this for elementary school outdoor activities and school trips. It was only used for the round trip between school, the bus, and the hotel, so it was not used in places that would get it dirty, such as mountain climbing or campsites. In addition, it was used about 3 times when returning to my parents' home by car, but since it was just moving between home and home, it was not carried on the back. It is in good condition, with no stains or stickiness, and no storage odor. A small backpack that can be removed with a zipper is attached. All zippers move smoothly. The only concern is that the back padding is not completely flat, but slightly curved in the direction of rounding the back. I'm sorry, but I would like to keep the price as is.
