The Specna Arms Knight protective mask is a unique balaclava and protective mask hybrid. Its most notable feature is the strategically placed mesh over the mouth area, which allows for easy breathing while also shielding the face from flying BBs. This mesh can be easily adjusted to fit the user's face shape by simply bending it - the flexible material will conform to your face and maintain its shape over time. However, be cautious of fragmented BBs hitting the mesh area.
