Was at Fontana today. (Honestly, what a great event.) I only found two outfits selling helmets: 1) stand21 selling only gear they manufacture themselves for race use - low 4 figures being the cheapest Snell helmet; 2) Winding Road Racing selling several helmet brands (Bell, Arai, Simpson, Sparco, Stilo and Black Armor...plus lots of other gear. Coincidence? Both are in Costa Mesa (although Winding Road is actually home-based in Austin, TX).
After trying on various helmets, I settled on a Black Armor (never heard of 'em) carbon fiber unit that fit great, has a bit of ventilation, and is Snell 2015 rated. Nice looking (if that matters) and did I mention? Fits great.
