9 multi-adaptable tension springs
The multi-band has nine circular section elastic strings that you can cut to adapt them to your weight or to personalize them depending on how you like to jump, run, dance, etc. The multi-band is equipped with four anti-collapse elements that facilitate a progressive compression of the whole system and reinforces the sensation of rebound in high tension moments. This element also helps to maintain the lateral stability and the fastening of the parts.
