IMO there's nothing better than slipping on a pair of nice, dry, clean socks during a hunt. I always leave extra supplies wherever I get dropped and socks are definitely one of those extra supplies. I usually plan on 5-7 days away from my drop point and carry 2 pair of socks in my pack. At night, if the socks that I've been wearing all day are particularly wet, I'll take them off, put on a pair of clean socks then put the wet ones on overtop, and go to bed. During the night my body heat dries the wet socks and my feet stay warm and dry all the while. The next day, I usually just wear the socks that I wore the day before since I like to try and always have a back-up pair of clean socks in case of an emergency. Usually during one of these hunts I'll go back to the drop point, somewhere in the middle of the hunt, and resupply. I usually don't take many extra clothes in my emergency supplies/cache and hardly take any extra clothes in my pack when I head up into the mountains, so when the time comes to get flown out, the clothes I'm wearing are usually pretty ripe since I usually have been wearing them for the last 10-14 days. The only exception to this is my socks, they are ALWAYS clean, and dry for the flight out.
