I have the button-fly rockers in X fabric, which is what they called it at the store. I really, really like them. I've got a pair of both APC Rescues and KMW 1980s, and the Rockers are by far my favorite. I sized down three, and they took their damn time stretching to a comfortable fit, probably 3 months or so of wearing them 4–5 days/week. I've had them for about 13 months now and I'm contemplating giving them their first wash, but I'm still up in the air. I love the way they fit now, and I think they'll last quite a while longer. They did develop holes behind each knee right after a couple of months. They're small, no bigger than a pencil eraser, and I left them alone and they haven't gotten any bigger. They've maintained their color pretty well, and the fades that have come through are mainly in the thighs and the back pocket from my wallet. I definitely recommend them.
