Would not use it. What I would use ( actualy I do Use) is a JT X-Fire ( aka crossfire) mask. Same lense, same general styling, same vintage ( well a little newer) but with todays safety requirements and guess what They still make them.
Dont use that old whippersnapper on the feild, its just not safe. remember your mask is THE most important peice of equipment you have on the feild.
