I think you might be dealing with a headshape issue more than helmet sizing. I find it odd not being able to fit an XL helmet but can fit a L size Shoei.... Ironically the GT Air 2 is also an intermediate oval like the CS15.
How much are you getting the GT Air 2 for? That's a huge step up from the CS15
Yes. Definitely is head shape + glasses issue combined.
My first helmet is a Magnum. Bought for learning bike.
It's loose and able to accommodate my head, specs and sun glasses.
Then a half helmet, quite squishy on crown but I have no issue with my glasses.
Just can't install intercom on this one.
3rd one, KHI open face, XXL. Loose, but able to let me wear with my glasses on, not inserting glasses after wearing.
This one is noisy as )(#*), at 60km I can't hear my intercom anymore.
Gone serious hunting for helmet since then, tried many brands / model over many shops.
Price range from RM250 to RM6000.
With design mentioning "glasses friendly".
All failed to take in my glasses while having a good fit, except Shoei.
Need to special mention GoMoto, Gene Advance and Takong Racing.
GoMoto (Shoei) measured my head and provided the first guidance for me on how to fit a helmet.
Gene Advance's boss taught me glasses should not rest on ear, and first timer's mistake about feeling uncomfortable to squeeze into the right fitting helmet, how helmet should stick with your head when you are shaking your head.
Takong's girl taught me how to check the gap of fitting around forehead and un-bias opinion on which helmet fits me, pro / cons of each helmet I inquired about.
The famous shop at Serdang, boss patiently took the trouble to bring out I think nearly different ones for me to try and all failed at me unable to insert my glasses.
Other shops were just pushing me helmets without guidance, only guide me to spend more even if it does not fit.
So ended up getting a Shoei open face as my first proper helmet.
All because of my glasses.
Not convinced about that, I took advise from some senior bikers and gone make 2 different glasses with straight frame.
One actually easier to insert into helmet, it's the one I am wearing now to go testing helmet.
Easier but still kinda hit and miss with non-Shoei helmet with my glasses.
Fast forward till today, after some serious riding trip, I have decided to give full face a try.
Hence the hunt for helmet starts all over again, trying not to just buy another Shoei, and to make sure I can stand wearing a full face for a long trip.
Since have a new glasses that's more suitable with helmet, really want to try if I can go with cheaper helmet.
