it is very comfortable

I love the bright colors and craftsmanship. This is a well-made backpack made to last. My boys were going through backpacks like crazy because they dragged them on the ground, so I decided to buy quality bags that would last a whole school year. My advice for parents of littles is not to pick a light color (I chose yellow) because they look dirty right away. I was able to get it clean again by soaking it in OXI white revive. Two things bother me, one is small, and the other is why I deducted a star. A minor issue is the cup holder is on the side the zipper closes. There is only one zipper, so you have to pull out the cup to get to the zipper. It's an annoying but minor issue. What is a big deal to me is that I bought these backpacks because it claims the kid's bentgo box fits in the front pocket horizontally. That is how it is shown on their stock photo. It works vertically but looks terrible, in my opinion. I posted pictures as a reference. I kept backpacks because I love the see-through window. With a glance, I can see that they have their homework folder or jackets.
