Need to make an XS sizeOverall Review: See the review on the FLY Racing Default Helmet. I bought the Fly helmet to replace this one as an inexpensive one for doing training and practice. The Fly failed in less than 24 hours resulting in a fractured jaw. The Giro helmet protected my son with much bigger hits that the Fly and he walked away completely fine. Buying this one again! Protect you head, protect your face - buy this helmet.
