AXO Air Cage Armored Shirt AXO's best value in upper body full coverage safety. The Air Cage uses a specially designed overlapping PU molded back plate system that leaves no open gaps even when fully flexed. Securely pinned to a open foam base the back PU, chest plates, biceps and lower arm areas cover all first impact areas of the upper body. A built in kidney belt holds the lower body in check and reduces the amount of movement of the Air Cage on the waist area. The forearms and shoulder cups can be held in place with the stretch Velcro straps. A center zip aids in putting on the Air Cage while the stretch mesh under body base conforms to the natural movement and shape of the body.
