I’m looking for a super warm winter coat that will last me forever. Something that will keep me warm around -30 C. I’m thinking military surplus, because it should theoretically be more durable (right?).
Price isn’t a huge issue if the quality is worth it.


I think you have an overly optimistic view of military gear. The stuff I had when I was in the army in the eighties was absolutely atrocious. I’ve heard they’re doing better these days but I’d always go for quality civilian gear if i had the choice.
US military used to have a really good coat. Apparently one of the best, but they don’t make it anymore.
And my Estonian military boots are amazing
Do you mean the field jacket or an actual big coat? Generally everyone recommends having multiple good layers rather than a big coat that can make you sweat.
