I purchased a Proforce shemagh in OD/Black to bring with me to Afghanistan when I served in the US Army as an Infantryman. I never realized just how versatile such a simple piece of cloth could be. Protects your head and neck from sand, wind and sun. It wicks away sweat in the heat and keeps you warm in the cold. Not just a scarf, but a towel, light shawl or blanket, handkerchief, bandana, cloth bandage or sling, and more. I use it all the time, and never leave home without it. I purchased mine in 2008, and still wear the same one now in 2013. Well made, a good fabric, and will take any punishment. Color faded over the years after constant use, prolonged exposure to the sun, and frequent washing. Best purchase ever.
