During the 1970's, the Army experimented with two types of masks that were never standardized. The first was the XM29 Series which came in four different versions: combat, armor, aviation, and special purpose. The masks used a unimolded integral large flexible lens of transparent silicone rubber with a protective coating to enhance agent penetration and scratch resistance. Trouble with the lens coating led to redirecting the effort to the XM30 Series Mask in 1979.
