These are a decent rag wool sock, as long as you order a size larger than usual. I typically wear a mens medium, and the size large is as snug as I'd want it to be. They're warm socks. Fairly thick, mostly wool, in the 'rag' style which I don't typically like for actually hiking (I don't think they're as comfy for walking in), but keep around for sleeping in on cold nights, for home use, etc. Decent color.
