I have one. I think it's a large. I've only worn it 2 times, but plan on getting a lot more use out of it this summer since I just got my own boat.
I'm not really looking to sell it, as it fits great and looks sick; like I'm boarding with a flack jacket on or something.... Just in case things get real crazy during my set.
However, for the right price, I could part ways with it and use the money for a new rope! PM me an offer if you are interested.
