I bought this for my son's birthday. He is 3 years old and about 36 in. tall. The bag is really cute and looks pretty durable. I like the little pockets inside the front pouch. They can help things organized.
The only thing I am not too happy is the width of the bag that seems too wide. The height is good but the width is as wide as his body (from arm to arm). He may be a little guy but I am sure it will fit him better when he goes to kindergarten. Right now, he just carries the empty bag around the house.
