3 year old couldn't keep saying he wanted to be a race car driver "with a fire suit and helmet" for Halloween.  Then weeks later, he said he wanted to be a motorcycle racer.  This costume is perfect for BOTH!  Now whatever he wants to be for the that day...it works.  The helmet is a mask, not a ful helmet, but it works!  LOVE IT!  Highly recommend.  Got the 4 -6 thinking if would be a little large for my 4t-5T guy, but it's jsut right.
