Love my GMax helmet, the air flow is great, the sun visor is great. Very happy, and the light on the back of the helmet made it easier for others following us at night. Only change I would make is the chin strap I would really like a click latch with button relase like my other helmet.

Excellent helmet. Even in Texas the excessive venting keeps me cool so far. The internal sunshade comes plenty far down so you don't notice a bottom edge. Came with the light and also a chin guard to block incoming wind for winter. I chose 2 sizes bigger than measured. I would suggest one size up. I had the Opportunity to try on a XL and it was too snug for me so i went XXL. Shipping was extremely fast.
Bought 2 GMax 54s, arrived in 2 days. One helmet had minor damage and the replacement part was sent out in a few days. Happy with the service I received, would buy from them again.
I belong to two ATV clubs here in the central/northern Calif in the Sierra Mountains. Two other members had this helmet and I also like the idea of the face shield / chin guard rising up out of the way. The helmet is very comfortable and easy to put on even with wearing glasses. It is a lot quieter than the 3/4 helmet that I used to use. My wife also feels that I am a lot safer with this new helmet. This service was great and I got help with the size being the size chart may not be correct. The shipping was very fast and I recieved the helmet on the day that they said. Hats off to you all.
really like this helmet. the blue tooth communication system fits in it nice . bought two of these helmets. will buy the same kind when we need to get replacements.
Helmet shipped quickly. Tracking was good. Undamaged on arrival. Sizing chart was right on. Love the helmet. Fits snug, but next size would be to big. Wind noise is no more than my old helmet. Love the features. Also bought brake light kit. Love the lighting feature. Everything works great.
I purchased this helmet as a back up and I wanted to try a modular helmet. I am very pleased with the turn around time for my order, the quality of the product and the value for my money. I would indeed purchase another GM54s.
its an excellent helmet in terms of size fitting, material used, protection and weight. i love it but the only setback is that during sped riding noise is relatively high.
Firstly Im a newbie rider and I thought that a modular helmet would be ideal since I wear glasses.The video helped immensely in my decision, and I was very satisfied with my choice.I opted for this model because i always choose the middle of the range variety, and of course ,you always get what you pay for. The material and construction feels well made, the ventilation works well, the paddings are very firm yet supportive, and the flip up mechanisms and slide controls feel sure and sturdy,not wobbly or cheap. It is quiet on the freeway.The price is very reasonable.The added feature of a flashing light is a safety bonus.I think I'll get one for the wife, but in pink
It is very comfortable and does not pass the noise although at the time of delivery I got a broken piece which raises and lowers the glasses but had to pass this transportation.
Love the inner sun shield and the 11 (yeah, 11) vents. The included chin shield blocks wind and noise. Scott must have sausage fingers, because I have no problem raising and lowering the inner sun shield with the outer clear visor in the full raised position.
Visited the Jafrum office in Charlotte, N.C. while visiting friends in nearby Denver, N.C. My wife and I tried on four or five different modular helmets that I had researched and that were sold by Jafrum and without a doubt, this helmet was the best fit, the best comfort, and looks good, too. We wanted modular helmets as we wanted to be able to lift the chin piece when we stopped for gas or whatever. I like that the clear visor lifts without having to lift the entire chin piece. A great feature. I also liked the drop down sun shade. This helmet has all you need in a DOT approved helmet. Plenty of vents for cooling. We currently ride with GMax 3/4 helmets, but our Blue Tooth comm system doesn't work very well even though it has noise cancelling microphones so we opted to go for the modular helmets in an effort to have better communication between rider and passenger.
This is the third gmax snowmobile helmet that I have owned. The gmax helmets I think are the best fitting helmets for snowmobiling. There is one very big issue that I had with this purchase, when I received this helmet there was no nose cup with this helmet. I do not know of any other snowmobile helmet that does not come without a nose cup. Also the lens that was on this helmet was a single layer shield and would FOG up very bad. I had two go out a buy another shield for this helmet.(double) When I was shopping for that other shield I did look at other gmax helmets and they all came with double layer shields. With me not being happy at all with this sale I will never buy one more helmet or anything else for you again.
Solid , quiet, fits nice, but don't like that you can't put sun shade down when shield is raised.(can't get to the button) Also the shield release on the chin doesn't release as nice as I would like.
Great helmet. Fits well and is very quiet. I really like the venting and the extra brake light.
Strait foward, simple and good for the price.
Nice helmet .It is confortable.the sun visor works pertty good and the protector down my face works so well in cold .
This helmet, meets and exceeds expectations. The dual visor works flawlessly. The wide array of vents allow for customization in any weather. I own two GMAX HELMETS and I doubt I'll ever buy a different brand.
I ordered the helmet through Amazon and it helmet arrived on time and looked the part in all respects. My spirits were dampened when it didn't fit right wearing and taking it out was laborious. I faced this inspite of the fact that I had stuck to the sizing chart available on the manufacturer's web site.
This is the second helmet of this brand and model I have owned. The first one was actually used in the manner that no cycleist wants. I went down and the helmit did what it is designed to do. I walked away with nothing more than a sore ankle, torn cloths and stiff neck. I hit my head hard but the helmit did its job. I would highly recommed this helmet to anyone.
Other than that, it is a Superb Helmet. I would recommend it to Anyone. I use it daily and Really Enjoy it. It's not heavy,Easy to remove the interior pads & liner for cleaning. The light on the back is Great for foggy mornings or for traffic. Plus the Price is Nice. I hope this helps
