Knockerball® is a single chamber inflatable bubble with inner handles and adjustable shoulder straps. Knockerballs® range from 1.2 Meters (Medium) to 1. 8 Meters (Extra Large) and the size or fit is predicated on your height.
The size chart below is just a guide, sometimes waist size will make the ball feel tight, so an upgrade in size would be needed, while others may feel more comfortable in a smaller size.
When ordering your sizes, use this as a guide, don't worry we'll try to bring a few extra sizes just in case.
Our Knockerballs should fit anyone over the age of 6 depending on your height.
