I've had the fortunate/unfortunate experience:headscrat to have been knocked-out in expensive and not so expensive hats:clap:. The cheaper helmet I recieved a concussion, the higher end I had no headaches or the typical "black spots" in my vision:headshake. I'm in the bike industry -look online for close-out 2,3,-4 year old helmet models (limited graphic choices & sizes). I've seen Arai's & Shoei's for less than $300 US. The Arai RX-7, Shoei RF1000 and X-11 are three of the best ventilated hats out there. These three hats are also some of the loudest (who gives a rats butt when most of us have loud exhaust anyways!!!):bike:.Are there any less expensive alternatives to the Arai XD3 and the Shoei Hornet? I like the look of those..but not the pricetag.
