Keep It Close. There are so many uses for a SureFire Bandana that we can't imagine why everyone doesn't carry one. Soft, lightweight, and durable, this Made in the U.S.A. 100% cotton bandana does more than just wipe a runny nose. It can serve as everything from a signal to a sling or a tourniquet in emergencies. It can provide sun protection, a mask, or water filtration in hostile environments. Or, it can be sacrificed to start a fire, make light-duty cordage, wipe your posterior...Hmm...Come to think of it, you should probably buy two.
