We just rec'd this for my 7 year old and it is so cool. The "muscles" are great. The only reason for a 4 instead of 5 star is the following. The costume is thin, like all 1 piece costumes like this one. It velcro's in the back making it look a little cheap from behind but it does not from the front at all. Also, we ordered the 7-8 and it was a bit short and he is not tall at all for his age. That said, I would definitely recommend buying the boys boot covers and gloves, they add just a little more character to this costume. Over all, great for the price and would recommend!
