I am 6'1" 180 lbs with a long torso, and the large fits perfectly. I can wear it comfortably with a tshirt or with my patagonia nano puff. I wear it all the time around town, and on warm days snowboarding. The sleeves are long enough, and I really like the adjustable cuffs. They work well with or without gloves. The fabric is light and flexible, and adequately windproof. Go-to jacket.
