A handkerchief is the Swiss army knife of fashion accessories. Contain a sneeze, wipe a brow, or sop up a spill. Signal the start of a race, protect your nose and mouth in a sandstorm, or obscure them while robbing a bank. Or, y'know, just fold it into your chest pocket. These ones are made with devotion and care by the two gents behind Sturdy Brothers, who aim to make stellar versions of everyday items with time-tested, small-scale production.
