Comfortable & Effective Head Protection:

HITT Shield technology is comprised of a proprietary global patented formulation of NDF™ (Non-Newtonian Dilatant Fluid) combined with other uniquely combined active elements.   Non-Newtonian fluid is a fluid whose viscosity (or thickness) varies depending on the applied force or stress.  Depending on the force applied, the Non- Newtonian fluid can act like a liquid or a solid. “Dilatant” material is a material whose viscosity (or thickness) increases with the rate of strain (or force) applied.  In short, NDF™ will dramatically absorb and dissipate the energy from an impact instead of transferring that energy to the area the NDF™ is applied or worn.

“Defender-Pro” in 4mm thickness also available for even more protection for high impact scenarios ie. Professional Sports, Motorsport, Military/ Law Enforcement.
