Originally this Motorcycle Armor was manufactured under French Police contract and designed with the newest safety technology. Bright orange panels are a high-tech "dilatant" material and display properties similar to a non-Newtonian fluid: each stays pliable and flexible under normal conditions, yet instantly firm up under stress for maximum shock-absorbing potential. Each panel is sewn into the included mesh lining for wear under a typical police motorcycle jacket. The mesh lining is sized for a tight fit, but you could easily cut out the armor panels (which are the cool part!) and add them to your own custom motorcycle armor solution.
