Chris, one of the ways a Buff can be also used is as a splint/tourniquet/compress. Last year my wife ended up getting mild heat exhaustion in a really bad place (as in no help available for many miles, no way of getting any within a days walk. The shade of a boulder and repeated wettings of the buff and putting it over her head (evaporative cooling) worked wonders. Since they are a good sun block on your neck, I use them in the summer with a light visor as a lightweight sun protection system instead of a hat. I can't imagine not having the darn things now!
