The Dura Outdoor Pickleballs, also known as the Dura Fast 40, are a seamless plastic wiffle ball specially designed for pickleball. The name of the ball is short for “durable” and these balls live up to their name. Duras have thick walls and use hard plastic for the purpose of increasing the lifespan of the pickleball to endure rough, outdoor pickleball court conditions.
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.
The Dura Outdoor Pickleball is a heavy ball, weighing 0.92 ounces, it helps keep the ball flying straight even in windy conditions but also makes the Dura 40 a fast ball.
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.
