My two cents.
This review is more about sizing on this jacket. First, most people stated that the Theta AR runs a bit larger than most Arc'teryx textiles. My size is 6'2, weight is 180lbs and I'm a large in every Arc'teryx jacket style. I went with the large and you might want to consider this also. Now, If you're wanting to use the jacket more for street wear then down size to a medium. However, with a size large you are able to layer anything under this jacket, if you Ice climb or nordic ski in extremely cold conditions you'll understand my case then.
