This helmet is great at everything you expect a half helmet to be... almost.
The size runs a bit large which was exactly what I needed. After trying the HJC-IS2 XXL and the Bell Pit Boss XL, only this helmet fit me.
Also, this is the second GMAX helmet I have owned. I tried the others after having the GMAX for two reasons. One, I couldn't get a replacement head liner. Two, the elastic band that holds the end of the chin strap fails after about a year of use. But for the price, I guess it is a fair trade.
With this new one I plan to have a snap installed to take care of the elastic band and wear a bandana to help keep the headliner cleaner and last longer.
