These Tactical Gauntlets are a must have item to complement your Shadow Warrior equipment, and for safety as these gauntlets are Tough, Light Weight, and extremely durable, made from Eight 8mm x 240mm high quality aluminium rods coated with a hardened Black Matt finish. They have been tested and proven in competitive competition including the KMA Association Shadow Trials, and Mock Trials using live blades. They will protect your Ulna & Radius bone from excessive damage including soft tissue injury if struck, but only towards the aluminium rods of each Gauntlet. When Aluminium is struck with a sharp blade the the metal will tend to buckle or dent depending of the force behind the strike, as with Steel that tends to fracture with equal forces applied. These are an important item to have in reducing personal and unnecessary damage to your lower arms either in the Dojo or Field training.
