Ordered a pair and they just showed up. I'm 6' 165 lbs and a medium seems to be the best size. Waist isn't super snug so there is room for layering underneath and tucking base layers under. The belt loops and internal cinches can be used to take up any additional slack. I tried a small and that also fit, albeit very snugly. So much so that I was concerned that layering at the waist would be an issue. The absinthem color is super bright and looks sick--should be easy to spot me on the mtn now. In general seems to offer the super high quality of the Burton 3L gore tex gear (love the hover jacket). Gonna bust for use in this snow storm about to hit. Should be awesome.
