>>813922Are you just going camping or are you climbing Mt.Everest?
Cotton isn’t a problem 90% of the time and cotton cargo / work pants and t-shits are fine.
I would get synthetic “moisture release” socks and underwear though, and you’ll want a Polartec type fleece jacket and a GoreTex shell parka to go over it.
For boots, there’s dozens and dozens of different light hiker boots available but I’d suggest leather construction, metal eyelets and GoreTex liner.
