I need an XL so options are limited! This is a very basic helmet, but keeps my head warm and adjusts easily in the back to get a snug fit. You can remove some parts of the liner to open up some venting in the Helmet, but I usually don't use this until spring time. I've been using the G9 for ~4 years now and just got a new one as the "snugging" mechanism on my old one broke. There are still some minor issues with the construction here, but I ski ~60 days/year so am probably pushing this a bit harder than average. My older G9 held up very well over 2+ years and I am a fan of the ever so slight redesign of this model (mainly the logo on the front).
