In warmth, this jacket is equal to a fleece-jacket.
This jacket packs smaller than a fleece-jacket. That is the advantage over fleece.
If you are looking for a really warm jacket to warm you up when chilled; get a down-jacket instead. I gave 3-stars instead of 5-stars only because warmer, down-insulation would be better. I would be concerned about warmth in temperatures below 35-degrees even layering a shell-jacket on top. Unlike down, you can hike in this synthetic-insulated, jacket without perspiring.
I am 6'-2" tall, 210-pounds. The extra-large fits me well. The jacket is long enough. Sleeves are long enough, with elastic at the ends. The jacket is slim-fitting, but not tight. Not bulky. A very tailored fit. I could wear a large, but a large felt confining. The jacket does not lift up when you raise your arms. A very soft, pliable, comfortable jacket.
Two, good-sized, zip-pockets to put your hands in, or hat. Small, chest-pocket. Jacket zips easily. Resists stains (I spilled ketchup on it and it wiped off without a trace).
I was glad to find a normal-color offered, Navy-Blue, which was not shiny.
This is a very nice Summer, Spring, & Fall jacket.
