Developed by the D3O - Delta Three Oscar, the P9s are knee pads that use revolutionary technology based on non-Newtonian fluid principles.

The anatomically shaped knee pads are injection-molded from advanced polymers that mimic the principles of non-Newtonian fluids. This means that the material viscosity depends on the applied force, resulting in the product's unique softness while simultaneously providing superior shock and blunt trauma protection for the wearer. The used material is temperature stable and will function normally in a wide range of climates.

The pads are manufactured with multiple holes that increase airflow and improve air exchange to increase further wearing comfort. Thanks to this design choice, the P9s are best suited for hot climates where ventilation and thermal regulation are paramount.
The elements are inserted into dedicated pockets in the legs. Thanks to their carefully designed shape and increased flexibility, they guarantee proper fitment and compatibility with a multitude of brands and trousers models.

The Delta Three Oscar products have been field-tested by soldiers in combat conditions, making them ideal for military and law enforcement applications.
