Product details:

Flexible, super shock absorbing D3O) spine padding, removable (for wash of vest) Superlight mesh material vest. Strategically placed low profile. Padding in shoulder zones EVA Foam Certification: CE EN 1621-2 D3O Shock Absorption is a pantented, shock absorbing material, engineered with Intelligent Molecules that flow with you as you move, but lock together on shock to absorb the impact energy. D3O is rate sensitive meaning that when you move slowly, the molecules flow freely making it soft and flexible. At high speeds however - like an impact - the molecules lock together making the material an excellent shock absorber. The whole process occurs instantly, returns to its original state as soon as the impact is over, and is repeatable. These qualities make it perfect for any application where you need total freedom of movement, and excellent shock absorption. D3O is also extremely low profile meaning and integrates seamlessly into garments, so neither style or function has to be compromised.
