I purchased this backpack for my 10 year old son who's a huge fan of TMNT. He's just over 4' 7" so I assumed, by the image alone, that it wouldn't look too "toddlerish" for his age and height. I specified his age and height for parents who's child may fall into this category and may be wondering the same thing. This backpack is not for them. This backback is more for children 6 and under (I'm pushing it to say 7 because it depends on the child's size).
I told my son, who still loves it, that he can keep it; but, he can't take it out of the house. Each day I look at it I want to take it and send it back.
Based on the image, again, it seemed age appropriate. Nope. It definitely is not.
