By the time I finally got a pair of these, the only sizes left were X-Small and Small, and even though I usually wear a Medium in OR stuff, I read reviews about the new sizing running a bit larger - and I'm glad I got a Small. I'm 5'7", 130#, and the Smalls are perfect. These are the perfect length for wearing with ski boots and they have a tiny back zippered pocket for a key or card. Overall these are great. The only thing I'd change is put the reflective OR logo either on the bottom or the top, not in the middle above the knee where it's painfully obvious.
