Review on Giro Scamp Youth Bike Helmet for Recreational Cycling by Sam Hansen

I bought this helmet for my young son to carry in his bike trailer. It can be pulled down to a fairly small size that seems to fit him (he's had it since he was about 6 months old, head circumference 17 inches). The chin strap is harder to get small enough in my opinion, but I think we managed to make it small enough that I don't have to worry about the fit. One thing to watch out for - there is nothing preventing the button from getting pinched. Skin under the chin, so you have to be careful not to do this (and you probably will at least once or twice if your baby moves even a little, like mine did).
