Alright, to follow-up with a fairly brief review.
Btw, here's a list of the helmets I've purchased in the last 2 years to help compare:
1. Nolan N85 Vortex (for sale)
2: Bell Revolver Evo Skratch
3: Gmax GM54 modular
4: Shoei RF1100 Chroma
5: Arai RX-Q Vibe (for sale)
6: Vemar Eclipse Carbon Fiber
7: Bell RS-1 Airtrix Speedway
8: Shoei Multitec
9. Arai RX-Q (black/red/white, for sale)
10. Bell Star Carbon Joey Dunlop Replica
11. Scorpion EXO-1100 Sixty Six (for sale)
12. Schuberth C3 Pro
Here are some things that I like and/or are better than other helmets I've owned.
1. Sound: for sure, it's quieter than the quietest helmet I've owned and much quieter than the average one. It's also not just about loudness but the quality of the sound be that whistling, rumbling, turbulence etc. It has this nailed. At speeds below 65 mph (GPS not speedo) it's shockingly quiet and above that it's still the most quiet helmet I've used. Also, vent noise is minimal and the type of sound the vents add when open isn't annoying. FYI: I have always worn foam earplugs. I still wear them the few times when I'm not wearing my S-Plug earbuds, which are also earplugs themselves.
2. The visor: it's as clear as can be. Also, usage while riding is the best of all my helmets. To latch fully, you just push the visor down past a detent. For a little bit of air, you lift just past the detent. The next level is maybe open an couple inches. No levers or buttons, very simple. For example, the Arai helmet requires the snapping in of a little latch and though it seals well it's a hassle to open and sometimes I fear it will start to wear a hole in my glove. Also, the sun visor is dark enough and finally goes low enough. That's been a huge issue for me with every one of those visors, so much that I swore them off. It also comes with a huge Pinlock visor.
3. Visor ventilation: It has just one simple vent up front and it directs air up the visor nicely.
4. Helmet ventilation: it's cool here so I can't guarantee this, but with the front and top vents fully open I feel a lot of air moving through the helmet. I think they say 2.5 gallons of air per second.
5. Paint: these aren't super racy graphics (I have the one pictured in the first post above) but I have no interest in solid colored helmets. Nonetheless, the paint quality is as good as any I've ever seen as you'd expect for the price. I was glad to find a graphic with some white in it as I feel all or mostly black is like having a No-Vis helmet. Also, these graphics are fairly sporty which is what I like.
6. Weight: it's indeed pretty light though I don't have all the numbers to compare all my helmets.
7. Fit: this is obviously subjective. My Arai RX-Q helmets have been my favorite fit (in terms of lack of pressure points) so I think I'm an intermediate oval. In Arai I've been buying size small and though it's a little tight it's okay. My C3 Pro is medium and it's perfect. No pressure points and the initial fit is just a tad tight which should open up a bit. Man was I relieved about the fit and not having to exchange it.
8. Interior: the newest high tech stuff out there. Feels amazing and feels and looks of the highest quality. Also, the feeling you get of the overall size inside the helmet... you know, when it's on your head is just right, ie. the chin bar isn't too close or too far.
9. Viewport: I'm not sure if it's bigger than any of my other helmets but it sure feels huge, like the biggest of any helmet I've owned. But not stupid looking huge or anything.
10. Aerodynamics at speed: I'm not one that's ever had issues with this but I don't usually buy cheap helmets. Suffice it to say, I feel no lift and turning my head to change lanes causes no issues.
Lastly, one of the things that's unique in the design is the big neck roll and the second one that you can zip out. Also, the area under the chin is basically sealed though you can remove part of it for warmer weather. I can tell you that for cold weather riding, this helmet seals up like crazy and my head and face stay plenty warm.
UPDATE: I've read that some people are having issues with their boom mics. It's caused by the two (one not removable) skirts under the chin that extend closer towards your throat than most helmets. Let me just say when I first saw this all while installing the boom mic I was sure I was screwed. Some say they ride with the mic on the outside, or have to move the mic out of the way when they lower the chin bar. Just wanted to report that as long as I position the mic close to my lips I'm able to lower and raise the chin bar easily and with little intervention.
