Been looking at buying a quality softshell for quite some time..then I found this! 5'9, 157..bought a large with some apprehension but found that with a light baselayer and a medium to heavy fleece fits great, and that's without taking in the waist. Sleeves are a bit long but not a problem. Love this jacket, did a five mile hike in the upper teens, light snow and a pretty good wind with this layered over a 300 weight fleece and light baselayer. Bullet proof, warm and dry. This jacket is going to get a lot of use up here in the Idaho Panhandle and Washington Cascades. Got is off SAC, arrived in 2 business days,,, Fantastic!
