Go to your local shop and try on a bunch, see which one fits the best. For me it's the Salomon Patrol (click here), but I don't know if iit will fit your head as well as mine! Good luck!
ive got the g9 and its mad nice. way lighter than my last helmet. its sick its got vents that you can open or close. its pretty expensive but see if you get get it off steepandcheep
there are some super dope new helmets coming out this year. id wait til your shop gets them in and get in there, try some on, and get one before the good ones sell.
