This is my 2nd time purchasing backpacks from JoJooKids and my kids and I LOVE these backpacks. I've attached pictures of the first backpack (purchased last school year for my older daughter) and the 2nd backpack (purchased this year in preparation for my younger daughter). The backpacks are extremely sturdy. The straps are wide with good padding and provide lots of support and comfort when carrying heavier books or things inside. There are 3 zippered compartments to the backpack. The main one is very roomy and spacious to carry TK and Kinder lunch boxes, or 1st grade books, projects, and papers. The wall of the compartment (the side that's on the kids' back when they wear it) is super thick and doesn't flop, bend, crinkle, or crumple. The middle zippered compartments is thinner - we used it mostly for assignment folders. The front zippered compartment is the smallest but it can still carry something the size of a regular sheet of paper and maybe up to 3/4" thick. We used it for emergency undergarments in case of an accident at school. The overall fabric used for the exterior of the backpack is really thick and holds its shape.The pictures show an older backpack with UV fading and an almost torn off front carrying handle. Keep in mind that the older backpack has been in use by a TK kid for a year and always hung up at school outside the classroom in the sunlight. Other than the front handle, the rest of the backpack is still as sturdy as the day we bought it. We haven't felt a need to replace it with a new backpack for the next school year (which won't happen now because of covid). The fabric is water resistant, if not outright water proof. We haven't dunked them in water to test but we have had water bottle and food spills inside the backpack and cleanup has always been as easy as wiping the fabric down.Hands down the backpacks are well worth the money. We do plan to repurchase these backpacks for our kids once the current ones are worn down, but that might take another 1 or 2 school years. In the meantime, these are also great gifts for our elementary aged nieces.
