Great mid weight/warmth/looks puffer. Good for ~ 40 F with a few med shirts of layers........~30F with heavy fleece layer and same few shirts, doing light activity...eg casual walk. I'm 6'2'', 180 lb andX L fits perfect to be worn either of former two ways. The two hem elastic adjustments are  a necessity to assure draft free/heat retaining qualities, and quit surprised to see this feature missing on many others like puffers. Plus, Columbia is a great value proposition...........above average quality for a few bucks more than inferior generic outerwear. For example, the shell/outer, is nylon, more expensive and far more durable than polyester shells......key if you any kind of activity ie it will last!
