this is an outstanding helmet. I deducted one star simply because I needed to purchase a 3rd party foam fit kit (also from Amazon) to fill in some of the non-vented empty spaces and get the helmet to fit properly.I am a daily commuter with a roughly 20-mile round trip, all on city streets. I didn't understand it at the time but the sunshade/ballcap bill of the helmet has turned out to be a real star. I used it (and several bits of gorilla tape) to affix a rear view mirror-on-a-wire in a way I never could have done if I had been trying to affix to the helmet itself.The chinstrap buckle is convenient to adjust and attach/detach. Not something to take for granted if you are taking it on and off all the time. The helmet is very comfortable and that same chinstrap is not noticeable to me as I ride. Another thing not to take for granted. As to protection I won't know until I bash against something but it certainly seems well made and if Bell doesn't know how to make a safe helmet nobody does. I did very much like the helmet's protection of the back and rear of the head.The clip on the back holds a Blackburn Twofer light securely and in perfect position like it was made just for it, which it may have been since Bell sells them on their web site. Keeping a light high up to the rear like that is a BIG safety bonus in an urban setting.Lots of little thoughtful touches on this helmet, when you add them up. If Bell could include - or sell - a dedicated fit kit for those who need or want them this helmet would be perfect. As it is, its still very much worth the money and then some
