Abstract: Two semi-oval pieces of fabric form an elastic pouch attached to a nylon belt. Both end's of the nylon belt are attached to a male and female buckle that secure the belt around the participant's waist. To accommodate different waist sizes, the length can be increased and decreased through a three strand adjustor. The fabric's stretchability allows it to expand and decrease in order to hold one to three tennis balls without falling out of the pouch. When the Ball Belt is not in use, it's flexible construction can be rolled-up, folded or used as a case to carry the tennis balls in.
