The burst proof fitness ball: Powerball ABS – the original made in Germany. The great physical barrier guaranteed. The special material ABS (anti-burst system) is latex-free, odorless and very load-bearing (in total up to 500 kg and additionally with guaranteed space safety even if the ball is up to 90kg). The safety system functions similarly to an airbag system in the car: in the event of damage to the ball by e.g. Sharp edges, needles, glass splitter, scissors, etc., the Crylon safety material prevents the ball-skin from tearing open. The air passes slowly through the hole. A plating is excluded and injuries caused by an unexpected fall are avoided. We guarantee this as a manufacturer.
