Jugs Indoor Pickleballs are our best-selling indoor pickleball. This type of ball is made of soft plastic. This soft plastic ball performs well on smooth hardwood, tile or cement court surfaces.This ball's softness and slightly-textured surface helps increase the ball's bite and bounce off the ground. All indoor balls are designed with larger holes and are lighter than outdoor balls. The Jugs Indoor balls measure 2.875" in diameter and weigh only 0.81 ounces, the lightest of any regulation-approved ball. These balls also have the most pop in them, proven by their substantial average bounce height of 37". These feisty balls are a favorite among countless pickleball groups. Due to its fantastic bounce and great performance, this is the ball that we at PickleballCentral play with on our court.
