I've spent more time than most (I think) researching what Down jacket to get. I have a Montane Anti-Freeze which I would have purchased again, but they downgraded the fill from 800 to 750 and kind of stylized the jacket for no good reason, which makes it a bit worse from my POV.
I live in NYC and just got this Mountain Standard -- had one night in the 20's and been in the 30's since. I"ll try and add to review when it gets colder. This jacket looks fine in NYC, which was a goal, the other being to stay warm, and the final being possibly a real "outdoor" coat.
The Mountain Standard looks a little a little more hip than most puffy jackets where many look like they're made in the same factory just with different logos. This MS website doesn't list the weight of the coat, which would be helpful in many ways, but it's light (please add weight). I like the zipper, don't like the too small inside pocket on right side, like the big pockets on outside, not super technical (hood adjustments are minimal), overall it's a coat that will get worn often in/round City -- if you're looking to belay in this you may want something more classicly puffy. Overall, works as advertised and has a bit of craft and individuality to it which is a big plus.
