A masterwork! Size M fits just right for 178 cm and 84 kg, but L would also be good, maybe even more comfortable—in fact, I had a big dilemma about which to pick, and M stayed for now. The L is only a bit bigger, actually fits better, but I kept M so that it's just right, even with a sweater. So, all this talk about taking a smaller size is not true, and I'm not a big guy. I have an average build. Material and workmanship are excellent—truly, probably the best company when it comes to this model. I was also convinced by the better sleeve cuffs, two-zone, with one half near the hand being denser and more snug. This demonstrates higher manufacturing care and that's indeed the case: the outer material is solid yet pleasant to the touch—top quality—and not too expensive. For me, probably the best jacket I’ve had so far. Comfortable and elegant. What also surprised me is what others wrote: it's warm, and it really is! Even though it doesn’t fasten up to the neck, the jacket alone keeps me warm, even at -8 degrees, when I only wore an undershirt and a thin jumper under my neck. Honestly, I was really surprised! Excellent protection. Solid material, lightweight, extremely comfortable and warm. Those opinions about the zip not working smoothly or needing waxing are completely untrue—absolute nonsense! The zip works smoothly, probably one of the easiest and smoothest I’ve had on jackets. No resistance when catching, fastening, or unfastening—it works perfectly. As for it coming undone on its own, which some have written about, it’s due to a so-called special military feature, with a sort of arch above the zip, which releases the lock and opens the zip when pressed from above—an auto-lock zipper. The jacket is brilliant. I'm attaching some photos to show the workmanship.
