Love it I love the helmet. I wore it the most out of the three i have. Sadly i went down in mine bounced my head off of the pavement. it did its job well. I will be replacing it. April 6, 2016
Nice helmet, but unnecessary visor I like the helmet, and the stripe on it. It's cool that it comes with a tinted visor and a clear one, but it is virtually useless. When the visor is down it seems to channel the wind right into my eyes. But this is on a bike with no kind of airflow management. March 15, 2016
On the overall I really like this helmet. I like half helmets as a general rule. That being said this helmet met my requirements It comes with a neck cape which is on the short side and does not cover my neck as well as I would like. The cape goes on easy enough. The helmet came with two visors one clear and a dark one. They change out easy enough. No tools required which is very nice feature when you run out of day light and need to change to the clear one,. The one thing I did not like was that I wear glasses and they do not fit under the visor easily. But hey, I still really like this helmet. The matte black looks great. The sizing was good. I have a large melon the sizing chart said an extra large would fit. and it does sit very comfortably on my head. I got the helmet too late into the riding season to say if the air flow through the helmet was good or not so good on a hot day, only time will tell. I can tell you that I am very happy with the helmet. The short comings I noticed should not stop you from buying the helmet. I mention them as it is better to know up front then to be surprised.

Great summer helmet Good looking summer helmet. Enjoy the flip down sun visor just wish it would come down a little more October 26, 2015
Wife loves it. Fits well. Looks good. Excellent helmet. Fits well and looks good. Price is awesome. September 21, 2015
Great looks and fit. Fits well and looks even better. Outfitted mine with the Sena 20s and sounds great. Bought 2 for the price of most single other half helmets available locally. September 21, 2015
Scuffs easily, useless visor, great helmet The drop down visor is totally useless to me. Wind wraps around it and it's easier to see with nothing than with the visor. The matte finish scuffs easily as well. Nonetheless, the helmet is comfortable, smaller, lighter than other halfs I've tried, and it doesn't catch wind anywhere near as bad as some of the larger ones I've tried. Overall, good helmet, and I'm not complaining about the little issues at this price. July 27, 2015
"Mushroom Top" The helmet is well made, but has a definite mushroom top look. Its quite large for a half helmet. I returned it. As usual Revzilla makes the process simple. Helmet is well constructed and comfortable, but I could not get over the way it fit and looked on my head. September 5, 2015
