This Djembe Hat will fit drums 12 - 14 inches in diameter. It is constructed of heavy material with an elastic band around the base for a secure and snug fit. The top of the hat has foam padding for extra protection. These hats look great while providing protection for your drum head against the damaging effects of sun and rain. I use a hat as extra protection even when I carry my drum in a case. When ordering, be sure to measure the absolute outer edge of your drum, including the hoops and lacing.
