Hey all. I wear a size M Ionos. My noggin is what I would call a Medium-Large - somewhere between the two, since I wear a large Pneumo.
What size Advantage 2?
I tried the top of the range Giro road helmet, found my size and ordered the Advantage in the same size… I find the advantage tighter, but I can use it. I would order one slightly bigger now, just to get a bit more air flow…
I wrote a piece on choosing helmets here. Hope it helps…

Agreed! The Advantage is definitely a little tighter. I bought a L, and it fits fine. I would like it to be just a little bit tighter on the head, but that would mean a smaller neck region - which I want as large as possible for T1.
Otherwise, it works great!
