I prefer liners and outers.

the D3-A military wool and leather combo lasts a surprisingly long time.

More puritan than the puritans? Sure, let’s start with I don’t know and then speculate.

You should try r/Boots

You want something resoleable made with decent materials that can be used in multiple situations. Thursday is a good place to start. Have you looked at Jim Green boots? There might be something there for you.

Also there are an absolutely stunning number of big time youtubers who focus on boots. Do a search and spend a few hours on the best boots for the money videos. I like Rose Anvil and Stridewise.

My son wears them as regular shoes 24/7 he goes through a pair a year.

Light, Warm and Durable are three things that don't really go together well.

I'd steer you toward a down jacket, as it's more durable than a synthetic fill and still light and compressible for traveling. The key durability factor will be the outer shell, so nothing too lightweight like a ghost whisperer.

How about a Mont-Bell Upland Parka? Or maybe a classic Marmot Guides Down Hooded Jacket? If you want synthetic, maybe a Rab Nebula Pro.

Maybe it signals that. Didn’t Westinghouse go bankrupt failing to complete plant vogtle in Georgia? Maybe this will revitalize them.
