This was a birthday gift for my 6yo grandson. He likes it very much, pronouncing it "cool, Gramma!" It's a wonderfully clever product.
Having said that, it's a very thin fabric - not a "sweatshirt." At first this put me off a bit, but then I realized that he can wear it as a regular shirt in every day circumstances, such as school, rather than over a regular shirt. It also runs small so buy one size up.
It is, however, very expensive for the quality provided.
A clever design, the Raptor Kids Hoodie Shirt forms the head of a prehistoric creature when one elbow is crossed over the other. The Raptor kids hoodie shirts full-color graphics bring them to life. Be warned, you will have to contend with your kid running yelling, RAWRRR!
