H Pentagon is a brand of top specifications at a global level that, as I understand, does not do marketing and thus manages to offer a product better than the more expensive ones, for example, Canada Goose, at 1/6 of the price. Amazing specs, strong shape/design, impeccable construction. My experience with this leads to the recommendation: you get it and you can't believe the bargain you found.

Regarding sizes, keep in mind that they are large (like many parkas), meaning that even if you have a broad bodybuilder physique, if you usually wear a large, get the medium and you will still be comfortable even with thick clothing.

Of course, when you zip it up, it gives a slight dolman effect (widens downwards like all thick parkas) and the long arm of the law (pockets, zippers, etc. resemble tactical equipment), but you don't lose in any stylistic battle because it is very experienced. Of course, if you insist on showing off your abs, leave it open. The profile and back (like with an open zipper) are aerodynamic in every arrangement. Some other models (e.g. the LCP, although it is considerably shorter, so there is no direct comparison) were a bit clumsy for my taste, but this one is the big boss.

Finally, although it is for -30°C, due to the materials/construction, you can wear it even in very mild weather (e.g. around +15-17°C) without feeling overheated if you move slowly (walking, shopping, etc.). It is important, of course, to note that while wearing it outside in cold and windy conditions, it feels like you are still at home, but it is not completely waterproof. The water resistance of fabrics is measured on a scale, it is never 100% absolute, and especially a thick parka needs to breathe in order to avoid sweating - unlike some plastic waterproof materials. As a reference point, Gore-Tex fabrics reach 28k mm/day, while this one is 10k mm/day. Practically, even in a downpour for 5 minutes, you won't notice anything, but then gradually the outer shell gets wet and if you stay in heavy rain or snow for a while, sooner or later you will feel moisture as water penetrates into the inner layers. Waterproof sprays significantly extend this time.
