Great light jacket
This Arc'teryx jacket is great-- it's warm but breathable, light and comfortable. I'm 5'10" and bought an extra large, and it fits fine. It's perfect for a cool spring or early fall day or a light hike.

Great Hoody
I have several Arc'teryx products and have always been very happy with the fit and quality. This is a great hoody. If you are familiar with the "Covert" line, it is the same great fleece fabric. The fit is a little fuller than most Arc'teryx items. It is not quite as fitted in the body. I'm about 5'11" and 175lbs and ended up with a Large. I usually wear a large in Arc'teryx items, but since this one fit bigger I also tried a Medium--it was too short in the body and arms.

Nice Warm & fit is great
This is a fantastic jacket that provides extreme warmth for its weight. I purchased this jacket for those brisk morning days and even for the slopes. This jacket fits true to size, even a bit athletic. But I'm 5'11" and 220 and need the XXL for the sleeve length, but the body is still baggy. Overall, Great jacket
