US M17A2 Gas Mask Review and Test

Review and test of the American M17A2 protective mask. The M17 series of respirators were cheek filter gas masks used by the US army from the late 1950s until the 1990s when they were eventually replaced by the M40 and MCU-2P. The M17 uses cheek filters which makes it fairly unique, cheek filters are ultimately a bad idea because they are impossible to change without removing the mask and difficult to swap even then due to stretching the rubber to insert them into the mask. There were three variants of the M17, the original mask, the M17A1 and then the M17A2, both the A1 and A2 had a drinking tube system. A lightweight silicone prototype XM-27 mask was made to replace the M17 but did not go into service, the even lighter XM-28E4 "Grasshopper" was chosen as a new design later on but also was not made in substantial numbers. Many nations made clones of the M17 to varying degrees of quality. The M17 is an interesting mask but ultimately a very flawed design.
