I've carried a bandanna since I was a kid. I used it for just about everything.
Bandanna's are a really cool item to own as you can use it to wipe you nose, dry your hands, clean up a spill, block the sun, cool yourself down and anything else you can think of.
Pretty much everyone in the west carried a bandanna, even business men carried a handkerchief and pocket square, which are more "refined" versions of the bandanna.
If you don't have one... get one.. if you have a few, get some more. They're super cheap and super useful. Just make sure you get the Made in USA 100% cotton ones. They're the best....
It's vintage gear for guys!
