This is a very nicely thought out and executed jacket. Really nicely constructed! Overall, very warm! Pretty thick layer of 800 down, baffled construction. Windstopper shell fabric. All the elements are there for serious warmth in the winter. I love the tall stand-up collar; perfect height to protect the chin and lower face all the way around. Great selection of pockets. The body is very nicely cut, it moves well. I find it to be the perfect length to provide coverage (down past the waist) but not too long so that it gets in the way. The (removable) hood is ok; but not a complete success. It is not quite large enough to come around front and fully cover the face. A bad design decision in a jacket intended for frigid/windy conditions. Other than that, my only concern is the sizing. I had heard in the past that Montbell ran a bit small; but that more recently they had re-sized their products to be more in line with North American bodies. And I have recently purchased a Thermawrap BC in size Large and it fits me well. So, I ordered this jacket in size L and it's not quite right. The body is ok, if perhaps just a tiny bit snug. But the arms are a bit too tight for me. Because of the tightness of the fit in the arms, I'm experiencing some minor cold spots around the upper arms/elbows. I don't have huge guns :-), so that's not the problem. I debated exchanging it for an XL, but I like the fit of the rest of the jacket the way it is. So I guess I'll just put up with it. So, my recommendation is that if you are normally a size L, and you want a close fit, stick with a L. If you would want to wear this jacket over other layers, you would probably do better to go up to an XL. But aside from the sizing (a personal issue for me), and the not-quite-full-coverage-hood, I think this is a superior quality parka.
