As to why these fine products are called zandanas, I must admit that I don't know. Then again, since what I don't know could just about fill the Grand Canyon that is neither here nor there - But any excuse for a quick Kevin Smith reference.
Tying a bandana properly can be a nightmare (Ok, that might be a little extreme, it's more of a mild annoyance), but these handy zandana's are already made up for your wearing pleasure, shaving valuable seconds off one's getting ready time (A priceless commodity for the unorganised among us). Available in various patterns and colours, so go nuts!
