You'll wanna try some on first, or at least make sure you check the sizing charts before you buy one. Giro makes great helmets, probably the most popular out there on the ski market as a whole. Bern and RED are pretty good too. I have a RED Trace and I love it. It fits my big head well, and its steezy with the goggles underneath. I have a Giro 9 too, and it fits my head nice and snuck and makes me feel protected.
