The helmet fits well, the wind noise is minimal and the look is awesome. The graphics are sweet. But my favorite is the built in sun visor no wait the awesome lights on the back of the helmet for safety ya that's the ticket. The best helmet I've had in20 years. and I've had a few!

This is my first full-face helmet. I researched other full-face helmets online and came across this one on as the best choice. You cant find a helmet like this anywhere else for this price that has all the special features that it has. It is very well protected, tons of vents that you can open and close, built-in sun lens, and so many more like the integrated led red light on the back of the helmet. I searched all over google and couldnt find any other website eith that feature which is a great saftey feature to have for people to see you more. I also just purchased a set of motorcycle saddlebags today from and cant wait to get them. I plan on buying even more accessories from Best site I've found for motorcycle gear and will reccomend to anyone!

I bought this helmet for my wife. The delivery was great as always , the fit was excellent and she really loves the dark visor and how simple it is to operate going down the road. The vents all work great. The light on the back is just an added bonus. I like it so much that I am going to get me one.
