Ok - so here's the good/bad about Helmet City:
The Good:
If you know what you want, and trust your size, they have great selection and price.
The Bad:
They have almost NO HELMETS in stock, nor are they set up to do retail. They are really an internet business. I drove all the way to Oakland and was not able to even try on ANY auto helmet, let alone buy one.
They Good:
They referred me to Ken @ IO Port in Lafayette. He had lots of helmets in stock, was VERY helpful, and had lots of other cool stuf besides helmets. I ended up geting a Bell M4 for $379, plus other goodies.
My conclusion:
Unless you know already know what you want, or maybe live closer to Wine Country than I do - go to IO Port!
Here's the web site for IO Port:
www.ioportracing.com
The owner, Ken, is a 20 year vet of racing and an instructor/coach for NASA racing/HPDE events. I highly recommend this place. Be prepared that the business is in a residence, but trust me...you'll be impressed with the stock and his knowledge.
