One of the problems for the fashion-conscious protestor in 2011 is figuring out what message you want to send. A bandana sends one message. A V For Vendetta/Anonymous mask sends another message. What if you want to send both messages at once? A V mask wearing a bandana just looks stupid.
Fold this bandana in half to transform into the famous fawksy provocateur from the comic pages. It's perfect for protecting yourself from sudden dust storms and outbreaks of authoritarianism. Keep your neck warm during those cold sit-ins. Use it as an impromptu rucksack to cart your gear from Zuccotti Park when the cleaners come. Cut eye holes to wear as a full face mask for added anonymity. Flag Fawkes. This is the hanky code for revolution.
