Optical has liked me the helmet. Unfortunately, he was not fit despite a head circumference of 55cm in size M. When I asked him a bit tighter, immediately began to push the wheel at the back. Normally I would therefore have to send him back, what would have been quite annoyed with the delivery cost. For fun, my husband tried on him, who has a much larger head - and amazingly, it fits just fine him. The practical test we make before next weekend.
