Multi Density By using a combination of specialised high-tech energy absorbing materials, we can provide protectors that are less bulky than our competitors whilst offering unrivalled protection. Nitrex Evo® This patented technology allows protection evenly across it surface. Most hard shell/plastic protectors will perform differently across its surface. Repeat Performance Technology The materials we use offer repeat performance technology. Hard shell protectors can only take one impact and should be discarded immediately after a fall. Flexibility A combination of Nitrex technology and Multi layers has enabled Forcefield to offer more lightweight and flexible protectors. This allows the armour to flex with the body and not be restricted by it. Breathability The unique triangular Nitrex outer grid has been designed to allow vent holes at the base which allows breathability but also reduces weight. Moulded Nitrex This contoured armour is available to protect the shoulders, elbows, forearms, hips and knee and shin. It combines Nitrex technology with a pre formed energy absorbing base and offers protection in excess of the current standard.
