An absolute must for a helmet is fit. My hubby's bike slid out from under him at low speed in the mud and was knocked out because his helmet was fitted incorrectly. Be sure that the helmet fits side to side and front to back as well as somewhat squeezing the cheeks. When you move it, it should move your skin with it. If it does not fit, don't buy it. I have to buy Vega's because of the shape of my head. My hubby needs AFX or Icon. MAKE SURE YOUR HELMET FITS YOUR HEAD!!! Oh, and by the way...I paid a whopping $19 for my helmet on Ebay, because I know what fits. Can't beat that for bargain!
