The triangular Bandana is a very versatile accessory. You can use it cover your mouth and nose as additional means of protection when you're out and about, or wear it around your hands, head or neck to keep away sweat, dust or sun.
Bandanas originated in western fashion where cowboys would tie them around their faces to prevent from breathing in the dust and debris kicked up by their horses. Nowadays, bandanas are worn the world over as a fashion accessory. Tie one around your neck, tuck one in your back pocket, or give your dog or cat that extra bit of fashionable flare.
