Fits like a glove. Size charts were accurate. The air vents work well. I used it the second day after I bought it. I mean REALLY used it when somebody driving on the left side of the road met me on a tight corner of a mountain road. As I went down. It bounced well on the gravel and protected my head from scrapes, breaks and bruises. My shoulder and ribs still hurt like crazy. (I'm too old for this.) But the helmet worked great and the gravel marks cleaned up quite well on the black matte finish. I'm very glad I was wearing it! Drove myself home.
Helmet is very good quality, size is right on and is very comfortable. Shield works nicely with 3 open positions. Very little shield distortion. Chin strap closure is very nice and easy to use. Just an all around great helmet and the price is fantastic. You can't go wrong, a good looking duel purpose helmet for this price.
