And it adds a dandy "flavor" to the water. Socks are a part of my survival gear. I always carry at least two pairs when out in the backcountry. One to wear, and a spare pair to wear if I'm forced to spend the so that I'll have something dry. Water in conjunction with something I depend on for thermal regulation doesn't sit well with me. I always carry a couple of bandanas. I would tie the bandana into a hobo style "bindle stiff" for transport. Of course if one has enough socks or a spare shirt sleeve or pant leg, those can work well too. Also a watch cap or something of that sort can be a good carrier (if you don't need it to stay warm that is!). I usually carry two caps (one light, one heavy), so "sacrificing" the lighter one isn't too risky.
