Jaycee1248wrote a review of Fox Racing Proframe Helmet on September 12, 2018
Familiarity: I've used it once or twice and have initial impressions
First was fit, the giro just didnt fit my head, it happens.. .
The rest is on paper, the fox is significantly lighter, and has more air flow.
my opinion is if you need to have a full face handy, you dont need the chin guard to come off. The fox proframe has all sorts of Chin bar flow and room to stick hydration hose in the front hahaha! The half shell of the giro is so big and covered all of your head, it's hot with or without the chin bar. the fox is a little cooler and I already have a half shell without ear coverage for hot, non-full face days. I'm an amateur rider, by no means a pro. but this is a great all around helmet, especially for shuttle days.
Theres no boa style sinch in the back like the giro, I dont mind it. the mips liner is different and fits fine. but if you're in between sizes it might be a hard fit. try one on at your local shop if you can, to get the right size
4 stars because they didnt have the color I totally wanted on sale hahaha its a solid 4.5 helmet!
overall I would say fit for me was spot on, needed a medium, and I have room for my hair to grow a little, or maybe a thin liner on chilly days. but not lose when it's short.
