Fox Flux Helmet
by Biker Bob in Colorado

I have worn a medium Bell helmet for years as it fits my noggin perfect. I was shopping one day and liked the look of the Fox so I tried on a small/medium and dang it fit great also. I have a round head therefore some brands don't fit well. Helmets need to fit well and protect well. Yay to Fox for getting this right for my head shape!

I am mostly a roadie and have several aero, lightweight and form fitting helmets that cost 3 or 4 times what this thing costs and none compare to the fit and comfort this provides!
