I tried the Montbell Frost Smoke Parka, TNF Micro Thunder, and Patagonia Down Sweater Hoody and Ultralight Down Hoody, and here are my observations.
The Montbell was the editor's choice at outdoorgearlab, but I found it had some shortcomings. It was not at all flattering, and despite the review saying that it was slightly longer than the Patagonia jackets, I found the small to be about the same length as the Patagonia XS. I loved the fleece hand pockets and the reinforced shoulders and elbows, but the hood adjustment is just mediocre. I don't think the Montbell comes in an XS, and I found the S to be too big and let too much of a draft in, so back to the drawing board. I'm 5'3", 115 lb for reference. Overall, a decent jacket if it fit, but the other jackets are way more flattering, and the hood adjustment of the Patagonia jackets are far superior to the Montbell hood.
Ultimately, I like the Montbell hand pockets and reinforcements, prefer the TNF Micro Thunder fit and length, and the Ultralight Hoody hood and exterior chest pocket.
