I bought this helmet a while back, I wore it to one track day, for about 30 mins. It has been sitting ever since. It is from a company called Zero 9, it is their Z9-APX. I really like the helmet, I am just not getting to the track enough. My loss is your gain, this helmet is practically brand new, it has a small white scuff in the top, it probably can buff out, probably set it down on something.
If you are interested please shoot me a PM or reply here.
