LOVE these backpacks, perfect size for my little guys. Regular kids backpacks purchased elsewheee have just swallowed them up! The fabric is perfect for those (more than occasional) spills, quick -drying, easy to clean. My boys love all the "secret" pockets on the front and sides. (I do too..perfect for water bottles, and sunscreen for quick access at camp) The colors are vibrant and fun, anything but a boring old backpack.. Finally someone thought of lil' guys & their needs!
