The Engage Tour Pickleball is made with “True Bounce Technology” that creates consistent play in any setting. These balls are intended for both outdoor and indoor use, but they play most similarly to a typical indoor ball thanks to their soft and controlled feel. This makes them ideal for players of all skill levels who want a ball that allows them to focus on their game. The Tour Pickleball is resistant to cold temperatures and cracks less in those conditions. They have a quiet sound and are USAPA-approved.
