D3O P9 Knee Pad

Protection isn't felt until it's needed. This is what D3O polymer allows, and it's why we keep these kneepads on instead of taking them off after an hour.

Flexible, then rigid

The material replicates the behavior of a non-Newtonian fluid: its viscosity depends on the force applied. Without stress, it bends freely. Upon impact, it hardens instantly and absorbs the energy before it reaches the joint.

Ventilation

The element features multiple holes that increase airflow and heat exchange. This is what makes the P9 suitable for hot climates, where thermal regulation matters just as much as protection.

Mounting

It slides into the pockets provided in the trouser legs. Nothing to strap around the knee, so nothing that slips or restricts circulation.

Compatibility

Designed shape and increased flexibility: it fits into the pockets of many brands and models of tactical trousers.

Temperature stability

The material is stable and retains its properties over a wide climate range.

Field-proven by military personnel in combat conditions. If ventilation is your priority, the P12 model in the catalog adds TriVent technology with triangular perforations.
