Nice. Good find.

They look warm. Throw a thin liner sock underneath them to nearly double the warmth.

If I had them down here the moths would have a field day. I've had a lot of wool I used up north lunched by the local moths. A pea coat, heavy wool pants and a 'wooly pully' sweater that together made up one of my favorite cold weather outfits didn't make it through the first year. The local wildlife wasn't impressed or deterred by the cedar-lined steamer chest. Ironically the items the bugs didn't touch were all items I didn't much like. Evidently moths share my tastes in wool clothes.

That's when I switched to synthetics. They don't have the same cache but I can stuff them into a chest, return after a year or three, and have a reasonable expectation of finding them intact when I need them.
