The Phalanx was one of the first successful low-profile gas masks. It was prominently featured in the Terminator 2 movie when worn by the riot police during the raid of Cyberdyne Systems Skynet building.

 A snug and comfortable Hycar rubber Ultravue facepiece with single low-profile canister, designed specifically for law enforcement and corrections personnel against riot-control gases. The Phalanx uses MSA Phalanx filters (7/8th screw thread) only and will not fit NATO 40mm filters unless utilized with the NOS-EXA adapter (included).  The mask is also distinct in its ambidextrous dual-canister mount, allowing the single required filter to be fit onto either side of the face. The Phalanx was intended for use with a rifle and the dual mount option allows officers to choose which shoulder they want to keep free.  Compact size allows easy integration with most visored police helmets.


Additionally, this mask is supplied with a NOS-EXA adapter allowing the use of any STANAG/NATO 40mm standard filter when connected.  Simply remove the adapter for use with the MSA proprietary Phalanx Mask filter.  For additional information on this adapter please visit


Each mask will also be supplied with one Expired CBRN filter at no additional charge.  We are not guaranteeing the integrity of the vacuum seal on these filters.  They are "AS-IS" and provided as bonus item with your purchase.
