GMax GM54S Helmet

Comment: Got 1, ordering another for a passenger. Fits great works good. Love the sun shade. Opens easily with one hand. Finding vents takes some getting use to.

I Love My G-MAX

Comment: This helmet wasn't my first choice , my first choice was too small and the wind noise was terrible I have to admit that I was weary about ordering a helmet online but Jaffrum changed my mind after allowing me to exchange for this G-MAx helmet which is the best helmet that I have ever had. It's very comfortable ,the sunshield works flawlessly blocks out the sun with just the right amount of shading .also it is top quality After having my head slammed to the payment during a recent accident I have no head injury .I now need another helmet and won't think twice about ordering another one . Thanks JAFFRUM
