Summer has just slipped away while I was lazing around... I imagine many of you have been looking for this! Unfortunately, it was a bit too tight for my large head (larger than average for a man), so I gave up on using it and it's been stored in the closet for several years. I only tried it on after purchasing it, and there are no sweat stains or noticeable dirt. (I couldn't use it even once) I think it will sell out in an instant once the season starts, so I recommend purchasing it now for next year's rides. * Size: Free Size (There is a rubber adjuster on the back of the head) * The photos on the 2nd and 4th pages are not "sweat stains," but light shadows. * The photo on the 4th page is the back side. * I don't have any pets. * I don't smoke. To prevent any issues, please understand that no returns, no exchanges, and no cancellations are accepted!
