Maybe o/t -
What are your favorites for thermal underwear? I have some Duofold that I really like - but I can't find in stores anymore.
I tried Hot Chilis but really unimpressed, and a few others but forgot why.
My favorite now is just some cheap thing I got from a thrift store and cut off the cuffs.
Socks are the same way - I find something that I really like and they stop making it the very next year.
The old orange and blue Ultimax were the best.
