I was between a medium and large, and often wear a skull cap under my helmet. So I went with the Large. Works great.

Great Helmet. I had one before and my wife accidentally dropped it on the garage floor, so she gave me this one as a replacement.
It fits well and doesn't catch the wind as bad as some of the other helmets I have used. My neighbor checked it out and liked it so much that he had me order one for him. Jafrum did a great job getting it to me, I ordered it Saturday night and had it on Thursday morning.
The Gmax brand helmets, whether it be a half or open face, fit my head as well as a helmet ever could. The GM45S is the best everyday use helmet that I have ever owned. Been using them for many years. I have never had a problem with any of the Gmax. Quality is good. Comfort couldn't get any better. I like the GM45S for my everyday so well that I just stocked up on a couple of extra.
Good fit, sizing chart was helpful, great quality for a great price
Hey, it's black, it fits real well. What more is there to say?
Awesome fit and looks. I was amazed how fast the shipping was to hawaii! Mahalo
I purchased this helmet about three weeks ago. The fit was on spot and the look was great. No bobble-head. This helmet saved my life. I was run off the road and crashed my motorcycle. The helmet protected my head, no concusion and no blackout. It did the job and then some. I will buy this helmet again.
Great helmet. No wind whip. No neck strain. Rides low. No pop down visor. Very comfortable. It is by far my all time favorite helmet. I have 5 different styles of GMax helmets. All of them fit like they were designed for my head. I just hope they aren't going to discontinue this model like they have the GM55S but just in case. I stocked up at $36.95 a pop. As far as I'm concerned that is one heck of a deal. Thanks GMax: If you read this. Don't stop making it. it's a great product.
