Onix Pickleball Balls are designed and optimized for the sport of pickleball. Onix pickleballs are available for indoor or outdoor play. The Onix Fuse is the indoor pickleball of choice and delivers the most consistent flight available. For outdoor play, we recommend the Pure 2 Outdoor Ball which was designed with a heavier weight and smaller holes to reduce the impact of wind during play. Our outdoor Onix Pickleball balls meet USAPA requirements for outdoor tournament pickleball play. Be sure to shop our 3, 6, and 12 pack Onix pickleballs to save even more.
