Box arm guards pack on more protection than regular field models. We like the Revenant Pro models because they are really a cross between a box pad and a field pad. If you are a field player looking for that extra confidence to back in or get to the cage, these pads are awesome. Form fitting and comfortable, with an elbow sleeve that will not pinch, these pads stay securely in place. Worn by some of the best of the best that you see on TV on Saturdays .
