GMax GM54S Derk Modular Helmet
Absolutely perfect except one thing
I absolutely love this helmet. The light helps a lot at night (not so much during the day), and it is obviously really cool looking. It's super comfortable and easy to put on without ruining my hair (big bonus) mostly because of the modular capabilities. Absolutely love it.
One thing is that the inside visor fogs up heavily from my breathe and I'm not sure if I'm doing something wrong or there's a mouthpiece I lost somewhere in the packaging. Cracking open the visor a tiny big helps fix the problem but I feel like that shouldn't be a problem in the first place.
Also the decal is peeling a tiny bit (not one that can spiral out of control) around just above where the modular screws are. It isn't noticeable unless you're looking closely at it though so no big deal.

Good bang for the buck
I've had this helmet for about 5 months so I can't really speak about long term durability. I bought this helmet for several reasons. One is that it can get painful pulling off and putting on a helmet several times. As I tried on many different helmets, my ears felt like they were being ripped off and were sore for several days. Being a modular helmet, you can flip the front up and get in and out quite easily. No pain. You can flip the front up and carry on a conversation, or just get some much needed fresh air on a hot day.
I like having the flip down sun shield. No need to have a tinted shield for the day and clear for night. Adds great versatility. It doesn't operate as smoothly as some of the the others on the market, but still makes life riding west in the afternoon so much more enjoyable.
It has a tail light built in with a couple if flashing modes to aid in visibility that can be wirelessly connected to your brake lights with an optional kit.
Price was very reasonable for the helmet and all it's features. I got it on sale, but even if it isn't, i still think it's a good price.
Fit and comfort...
It fit me just right and felt very comfortable right away. It is a bit heavy, but most of my riding is short trips around town or an hour down the road. It does, however, weigh on you with longer trips. I did a trip including Oklahoma, New Mexico, Texas, and Colorado in only a couple days and I was really starting to grow weary of the weight on my head. Also, and I'm not sure if it was the helmet or the result of wearing a balaclava (cold front moved through) and it's stitching, but I started feeling a lot of pressure towards the front center of my head. It became quite painful towards the end of the trip. It's possibly the balaclava, as the stitching is right down the center of the head. However, I have not made that long of a trip with this helmet without the balaclava to know for sure. There is also stitching on the liner in that general location too... It's possible the extra pressure from the balaclava coupled with the helmet made it that much more uncomfortable.
It does have decent ventilation, but will fog in colder temps when you aren't moving or moving very slowly. I have worn this helmet in temps from right at freezing to 110° F. It handles it all okay.
You definitely want to wear earplugs at highway speeds. You should regardless of the helmet. It does whistle a bit at high speed when you look to the side or if there is a strong side wind.
Overall, I'm very pleased with my purchase and I think for the price it can't be beat. I am planning a long, almost cross country ride late spring, so I may update then.

Best Bang for Buck
I originally bought this helmet in black for my wife; since she seldom wears a full face I adopted the helmet for myself because of the integrated sun glasses. After having this helmet for a year I'm a huge fan; The integrated sun glasses make life easy in the early or waning hours when the shadows cast across the roadway (I can quickly switch back and forth). The modular face makes it easy to get on and off with my neck gaiter on in the winter time. I've also become a fan of the red warning light in the back; I turn it on in the evenings and almost always in the rain for increased visibility.
The helmet is somewhat heavy compared to the more expensive brands, as I assume the road noise is also somewhat more noticeable. I ride with a Scala rider headset which is more than loud enough to drown out the road noise, so that's of no concern for me. There are a huge number of vents on this helmet, so I'm very comfortable in the summer time. I don't typically hang out in the city on the bike for very long, so I imagine it might get hot at the stop lights on the hottest summer days. Inversely, you'll need the Balaclava for winter because it's still somewhat drafty in the winter even with the vents closed; but keep in mind I ride well below freezing.
Ultimately I don't think you can beat the bang for the buck; well vented, modular, integrated sun glasses, and affordable. So much so I bought my wife a second one.

Good looking with nice features and fits well
As luck would have it, I have not been able to ride since my GM54S in Titanium came in in size large. So I but it on and sat for a few hours as suggested and watched TV. The fit felt fine. No head ache and the weight seemed fine. No neck pain. My head circumference is 22 1/4" x 8" length x 6" width. I guess this makes me an "Intermediate Oval" head shape. The only snug place is the cheek pads (I have a 5 1/2" wide cheek bone) but this should get better when pads break in.
The light looks better in hand than in the pitchers. Also the push button switch is flush so it is not to easy to find with gloves on but it looks good so I can live with that.
The face shield is easy to change as I put on the silver iridium shield. It took about 10 seconds to do.
The latch release to open up the flip-jaw feels solid and is easy to do with gloves on (Fly Street FL2 Gloves).
Only gave it a GOOD rating as I have not used it on the road.
The weather in NY is kinda bad at this time, but if it gets nice enough to ride I will up date on noise and "ride weight" of this helmet.

outstanding value as mentioned already in the reviews
The value is unbeatable as stated in other reviews.
I will make a comment on the fit.
I am Chinese like 1 out of 4 people on this earth.
My head is LLLarrgge, round and somewhat flat in the back. I have had huge problems finding helmets that fit. I tolerated other helmets but they always had pressure points. This is the first helmet that I can say actually fits me. I have tried on alooooot of helmets believe me and this one fits. This is my second helmet. The first one pooped out after 3 years. hope this helps those with big round heads.

Good overall helmet. Doesn't feel to heavy. Only downside is that a lot of air comes in from the neck area, making it a little chilly to ride. The visor fogs up but if you're moving it'll go away pretty fast.
