Very satisfying purchase! Bought this helmet for my son. As expected, was a 100% new factory package; packed well; arrived on day that was predicted. Fit is good. He believes it to be very good quality. Not too heavy. Looks awesome, he loves the graphics. We've already taken advantage of removable pads for cleaning. June 2, 2015
Excellent comfort, style Walks the walk. Worth the price: excellent helmet. This helmet was put to the test and passed. I fell going about 40 mph and the helmet did its job. Protect yourself, try this helmet. May 6, 2015
