Merino wool is a very different material then “classic” wool. Backpackers like it because it wicks sweat and it’s naturally antimicrobial so the smells dissipate over night. It’s also not itchy due to the finer weave.
My favorite is Darn Tough socks. They’re merino wool, warm when they need to be and cool when not, and if you get them on sale (only way to buy them) they’re worth the price. Lifetime warranty, so if you get holes, you get new ones. Last socks you’ll ever buy.
