The XM30 Mask had a large,
flexible bonded-in-silicone lens, which provided greater visibility than the M17 Mask. It had front and side voice emitters, a drinking device, rapid donning, and came in three sizes. The canister was developed by Canada and had NATO threads. The XM33 Aircraft Mask and XM34 Combat Vehicle Mask were similar. Marring of the lens and other problems resulted in dropping the XM30 Series Masks in the early 1980s.
