Thickened PVC: The inflatable bumper ball is made of thickened 0.4 mm high-elasticity PVC fabric, which is more tear-tough, and better sealed, and it is built to handle repeated inflation and deflation plus intense impacts

Secure Shoulder Straps: The strap buckles feature a deep textured design and reinforced stitching to help resist strap drop or accidental loosening during movement and impact. The body sumo balls are more stable and secure to wear

Hot-Melt Handlebar Grip: Integrally molded with a hot-melt process, the grip resists glue separation and cracking. The human hamster bubble ball is comfortable and snug in hand, and it provides a steadier grip on impact and more flexible control

Leak-Resistant Air Valve: The twist knob air valve tightens for a secure seal, making bumper ball's operation simple and intuitive. The interior features a multi-point sealed valve core design that helps avoid air backflow and leakage

Party Delight: You can start an action-packed bumping game anytime on the lawn, in the park, or on the school field. The ball is great for birthday parties, team events, family picnics, and school sports days—bringing fun and laughter
