This helmet was larger than I thought it would be.  I thought it would fit my 6 year old son (he has a larger head), but I was wrong.  the helmet is very large, it didn't stay on his head.  Every time my son turned his head the helmet was crooked due to the minimal weight.  It was very light almost to light which made it seem a little flimsy.  Very cheaply made - thin plastic.  Maybe this helmet would work well for someone whom it actually fits well, but it was not the case here.
