I upgraded from a 1000 to the GT Air.
Love it. Yes it was tight to get on my noggin for the first month or so, but very used to it now.
Yes, getting used to the drop down visor took some time, but I do like now. It's nice to slide it up in dark shadow stretches or the few times when arriving in dark.
The fit for me is beautiful. Snug, but comfortable without pain.
I ordered the 33 mil cheek pads as I'm currently sporting a full grill (upper/lower braces) and it's very comfortable.
Once the grill is gone, the original pads will go back in.
I really like that the head liner is fully removable and washable!
Yes, having a smoke or mirror shield would 'look cool' but again for me, the drop down visor does a very good job of diffusing the sun.
Having had restorative ear surgery in 2013, this was a major concern. THIS HELMET IS QUIET!
I've installed the Cardo G4 Scala with internal bluetooth speakers and only ride with one ear plug (in the restored ear).
I can enjoy the music and comm (between other rider) and have no issue with the wind noise.
It kills the low level buffetting that would come up from the chest and shoulders, through the neck area on my previous RF 1000.
The venting is quite good, and I can really control flow either over the face or forehead.
The only issue I've had thus far, is attempting to clean the pinlock screen as some dust/dirt gathered around the gasket.
This was my learning curve / fault. I've damaged the optics inside the pinlock, as there seems to be some kind of coating.
Prior to my meddling, there was no fogging or condensing. After, I do get a little fog when out in heavy rain.
Final Thoughts: I love the helmet. Expensive? Yes - but I saved up and found a deal for $450.
I need to replace the visor and pinlock screen, so I may look at the polarizing one, but the clear is still very nice.
