>>1032122>what temperature are these comfortable to?There's 2 varieties: The military issue ones that are generic polyfill, which is warm enough down to about 60*F as a standalone (they're really not very warm). Then the aftermarket ones that are Thinsulate, which are warm enough down to around 45*F as a standalone.
>I could easily see a liner working [as an insulation layer for breaks]It would, but take a gander at the "field jacket liner". Same material but sewn into a pseudo-jacket, designed to be buttoned into an M65 field jacket for cold weather. Military calls them smoking jackets or woobie jackets.
>bulky?Yeah kinda. They're not really compressible. However they don't weigh much (thinsulate ones weigh less than polyfill ones).
>looking like a tryhard tacticool wannabe?They make them in several solid colors as well as all the current and recent mil camo patterns. Doesn't get much less tactical than NWU or ABU pattern, and nobody's gonna give a shit if you get it in M84 woodland (which most of the surplus ones will be).
>Also, do I look like a wanna-be if I call it a woobie? It's fun to say.Generally only prior mil will get the reference, everyone else will just assume you're a millennial. The mil guys won't give a shit or congratulate you on knowing its "true" name.
