Top-notch jacket! I'm absolutely thrilled with it and love it. I'm 5'8½" and weigh 187 lb. I ordered a size S, and it fits like a glove. There's room in the sleeves, and it doesn't restrict my movement. I can even wear a hoodie underneath. The workmanship is flawless, and the outer fabric feels sturdier than that of Alpha Industries jackets. It keeps me very warm now that it's fall. I definitely recommend buying it. I've only had it for a few days, so I can't yet say how it will hold up over time.
