Great little backpack! i was actually impressed how much space there was in this little pack. I ordered this as a new diaper bag for my kids. I was carrying a full size backpack and it was too heavy with too much stuff in it we didn't use. So we downsized to this and it's perfect!Love the really large main compartment that includes a zippered mesh pocket. Perfect for a few diapers, wipes, a blanket and a change of clothes, hat and bib. The middle pocket is full of little pockets and card slots. We have sunscreen, sanitizer and Kleenex in here and it's great. The front pocket is really spacious and plenty large enough to hold a snack bowl and granola bar. Love the full size outer mesh pockets for sippy cup storage. Made of sturdy material and fits really well on an adult with the straps.It is small, but that's what I was looking for!! It is a perfect size for my five year old to haul around for me :) Would not fit a school folder, but it's got way more space than I was expecting and fits just what I need for a toddler and fiver year old. Love!
