Liven up any gathering with a single 5 ft inflatable bumper ball built for outdoor family fun. Durable 0.8mm Pvc makes this human hamster bubble ball waterproof, anti-static, and resistant to deformation, with strong seams and enhanced anti-explosion properties for long-term use. A high-quality valve seals tightly to prevent air leakage during extended play, while a polyester drawstring adds elasticity and durability. Ergonomically designed integrated soft handles pair with wide, thick, adjustable shoulder straps that relieve pressure and keep the player secure even if a handle slips. Measuring 1.5 m in diameter and 1.2 m high, it fits participants roughly 4.9 to 6 ft tall and 100 to 330 lbs, welcoming both adults and children. A user-friendly repair kit with two patches keeps the fun going, and one full inflation lasts up to 12 hours. Enjoy bouncing, rolling, and bumping in gardens, backyards, beaches, and parks.
