sock's, sock's and more sock's. Underwear as well. I can put up with the same shirt if I have to. Same sock's & pants? Noooo.......
I have found that polycotton walking trousers are to be prefered over jeans pretty much anywhere. Loose fitting top layer(s). Wind or waterproof as needed. Oh, yes. One other point - Any friend who left me in the cacky when I can't get home would be off the friendship list real quick.
