I ordered this because I'm coming to like RAB products. I have the Microlight down in Small and I wanted something to fit over for rain/wind protection. I ordered this in a medium, because it was all they had at the time. It fits, with a lot of room to spare. Sleeves are slightly long. It is not an athletic, slim fit, so the sides are a bit large. It does breathe well, and the stretch is appreciated. I like the fact that it has a velcro strap for rolling up the hood when not in use. The wire brim on the hood is bent easily back into shape after packing into the front pouch. I like the pullon for backpacking and hiking, less zippers. The pouch depth is limited when you have a waist pack belt on. Overall, I would buy again, in a small though. I'm 5'6" 160# 44"chest. 31" arm length. 30" waist.
