Since the town of Sancti Spiritus, Cuba is by the Yayabo River, some say the shirt was originally called the yayabera. Others say it was named for the tart fruit, the guava. Workers frequently wore the shirts as they ate their lunch in the shade of the guava trees. It even became the uniform of the resistance fighters in Cuba's struggle for independence from Spain. When people started moving to Florida from Cuba in the late 1880s, they brought the shirts with them.
