21 vent ports are scattered throughout the shell and are all submerged, so no foul tips will make direct contact. All the ridges in the shell increase the strength and durability of the mask, while at the same time make it look pretty stylish. Back plate features three “bridges” which force the snaps to stay hooked up. A strong center bar on the cage and its wedge shaped design, balls which target your mask will deflect off upon impact. The gap between the cage and shell limits the direct force which can be sent into the head. Removable liners can be machine washed to keep your mask feeling brand new over multiple seasons.
