The SCOTT Actifit back protector features the innovative D3O® Actifit plate. This plate is so low profile that you can wear the neck brace over it: it fits! TECHNOLOGY D3O® d 3o® material is a unique solution with the focus on energy dispersion in critical areas for maximum shock absorption & protection. The functionality of the raw material originates from the synergistic effects of the polymer based dilatants. Energy is distributed throughout the synthetic elastomeric polymer & the enhanced chemistry continues to distribute energy on throughout the matrix, significantly reducing the effect of impact.
