I am that mom who does entirely too much research. I really went above and beyond while looking for the perfect toddler/preschool size backpack for my girls. I wanted something sturdy because let's remember these will be carried/dragged by toddlers. I found several that had great reviews, but I didn't want to pay $25-30 for a toddler backpack (they get nasty, tear, rip or become lost). It was my lucky day and I was able to find these backpacks while they were Prime for less than $7. I was skeptical obviously because of the price, but the reviews were great. I decided to try for myself. BUY THESE. Super sturdy, perfect size to carry a blanket, extra set of clothes, lunch box, preschool papers/folder or whatever your little decides is important enough to go in there. We bought the purple and the aqua color. Amazing colors! I am also having my girl's names put on their bag (and for the price I paid for these I do not mind spending extra on monogramming). Perfect size for 3-5 year olds for sure! Not too big or wide. You could also use as an adult if you needed a diaper bag/hiking bag/etc. So happy with my purchase.
