D30 Back Protector. These are very flexible, compact and light protections, thanks to the D30 technology. D30 is a material which, in its natural state, adapts to the body's movements, but in the event of an impact, it agglutinates to absorb and dissipate the energy, reducing the energy transmitted before returning to their flexible state. These protections can be mounted inside the predisposed jackets. Certification CE EN1621-1 level 1. Approximate measurements: 44 cm (long).
