Guys,
I purchased an Ermax large in clear and installed it for about 20 miles. It's just not for me. I think if I was taller, it would be a GREAT shield to keep wind off your body, but not your helmet. I'm 5'5" / 5'6" and it hits me right in the head on my short seat. If anyone is interested in purchasing, PM me and we can work out a deal.
