I upgraded to a Giro G10 for this season. It fits far better. I was in between a medium and a large with the nine and bought the nine in a large so I could fit a balaclava hood underneath on cold days, but it seemed a bit loose with that. The G10 seems to run just a little bit smaller than the nine and my large G10 fits PERFECT! The slider on top to open the vents will be a nice feature and better than pulling the inserts of the nine out. Highly recommended.
I just bought my daughter one a week ago....My G9 is fine for me this year.
