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.
As someone who once believed the same as you, military surplus can really be hit and miss. It will either be the best that you have ever seen and built like a tank or the worst flimsy, rubbish bag with arms and legs that you have seen.
Edit: typo.
