I love them! I always get two years out of them. The small will fit standard size folder, and 1 inch binder , library books and I can still put their lunch box inside or hook it outside the packback. The larger outside pocket I pack their snack.. . I use medium for pre-k, kinder and 1st and move up to the large in 2nd.
2nd year they still look really good. I use to buy 15 to 20 backpacks and they never lasted a school year.
