The bandana or handkerchief was one of the most utilitarian articles a cowboy could have in his possession. It could be used as a mask to filter the dust when riding drag behind the cattle herd. It came in handy as a sling for broken arms or as a tourniquet. It made a good wash rag when needed and could filter dirty water for drinking. It was also great sunburn protection and good for weather all around. 

Nowadays the bandana print has become a trend being sported by fashion girls across the globe.
