The Dura Outdoor ball (DuraFast 40) is the official ball of the US OPEN Pickleball Championships, Spanish Open, Bainbridge Cup, PPF, and 2017 USAPA Nationals.
The Dura Outdoor Pickleball, also known as the DuraFast 40, is a seamless plastic whiffle ball specially designed for pickleball. They, like all outdoor pickleballs, have thick walls. The purpose of using hard plastic for a pickleball is to increase the life span of the ball in rough outdoor conditions. The name of the ball is short for “durable” and these balls live up to their name.
The ball is made by injecting a single glob of hot plastic into a mold. The mold is closed and rotated to spread the plastic evenly around the walls of the mold. When the mold has stopped spinning it is opened and the new ball is removed from the mold. Sometimes there is a minor separation seam from excess plastic that leaked out of the mold. This excess plastic is sanded off. Look inside the ball and you will not see a seam.
There are two sizes of holes drilled into this ball. The two sizes of holes and the hole configuration, help make the ball more aerodynamic.
The Dura Outdoor Pickleball is a heavy ball, weighing 0.92 ounces. This weight helps keep the ball flying straight even in windy conditions. The weight also makes it a fast ball, compared to the softer and lighter indoor pickleballs. The Dura is also a little bigger measuring 2.9375” in diameter. The ball has an average bounce height of 32”, promising lively response to every hit.
For many years, this ball has been the official ball for the USA Pickleball Association's National Pickleball Tournament.
