I bought a larger size this year as the M is too narrow for my neck and was not comfortable.
This one was purchased Fall 2006 in the 1st GP for them on this board. It is the 20M Economy model with quick disconnects. It comes with all helmet attachment hardware and paperwork that came with my new one. It has been used at 6 total HPDE days and is still in perfect condition.
$750 shipped.
