Its precisely-spaced holes reduce wind interference, and independent tests confirm its long lifespan. Its .88 ounce weight makes it a great option for all environments- from outdoor tennis courts to indoor gymnasiums. The SLK Hybrid Indoor-Outdoor Pickleball weighs .88 ounces (24.948 grams) and has a diameter of 2.85" and a bounce of 33.25". Made in China.
