Wear a bandana like a gang

A trend for young men is to wear bandana scarves around their head in the gangsta style. It’s a fashion that started among gang members in California and has since spread from the West to be a nationwide style among young, urban men. Everyone who wears the style isn’t necessarily a gang member, as it has become pretty main stream, but many times the colors or patterns of the scarves are indicative of gang loyalties.

Really bad idea if you are driving a motorbike without a mask like this in this contaminated atmosphere.
Here, only usage for cleanliness is most practical use.
Robbers love it sometime :-)
