For narrower heads
Reviewed by Trader x from Eastern PA on Monday, February 13, 2017
Solidly built and adjustment is top notch. The fit is definitely for narrower heads(not small, just narrower). This is for my 13yr old son and the sm/med does not fit. His head circumference is in the lower range of the size purchased. His current Giro youth helmet still fits, just trying to get ahead(no pun intended) for next year and beyond. Guess we have to stick with Giro.
