Our Neoprene Tactical half face mask features coverage of the lower face and at 4.0mm thickness it is almost double the thickness of our regular masks. The extra thickness is great for use with airsoft and tactical training where the extra face protection is needed. The neoprene fabric is warm and wind resistant and has nylon bound edges for durability. Hook and loop closure ensures customizable fit. Can be used with or without a helmet. One size fits most.
