It’s very warm and longer than typical vests, so a lot of your backside is covered. The sewing is top notch and it lays very flat, so it’s easy to layer with a jacket over it. I would only use a base layer turtle neck or long sleeve shirt with a collar under it, though. If you want to wear a bulky sweater or such, I’d say size up. It’s better to have your shirt or base layer cover your neck, as other reviews mention, because there is no flannel on the inside collar and the material is a little scratchy-- not horrible though. The arm holes are tailored just right, not too big or small.
I got a size medium which fits me just right. I’m 5’ 5”, 138 lbs. athletic shape; 34B; muscular upper body (which is why I didn’t get the small), narrow waist, muscular thighs. I called and discussed sizing prior to purchase, and the nice woman said I could probably fit the small, but it may be too snug. If it helps, I fit size small in Outdoor Research vests/athletic fit jackets; medium in Patagonia R1 & jackets; small in REI vests & lighter jackets, medium in Smartwool vests.
I’m very happy with the purchase, yet it’s really not for active pursuits as I was hoping for. It’s more of a nicely sewn, unlined, city / car camping jacket with the arms removed! I know I read this, yet conveniently forgot it in my excitement of purchase, that it says “dry cleaning only”. This means I won’t be wearing it for any active, sweaty backcountry or athletic pursuits, as it’s just not feasible to dry clean active gear on a regular basis.
But that’s ok, I’ve already worn it on some cooler fall days here in Seattle, and it will suit me well as a mid-layer or outer jacket with beach bonfires, city walks, car camping and such. If I am in an office environment, it can certainly be dressed up, too.
I assumed incorrectly after reading the history of the company that the item was made in the U.S.A., yet am disappointed to know it’s made in China.
Last, but not least, there is super friendly customer service!
