Abstract	A 32-hour field test of two prototype protective masks was completed with 16 men in temperate weather. The transparent, coated, silicone rubber XM29 mask, with a newly designed peripheral seal, was judged acceptable for long-term wear as was the rubber XM31 mask. The subjects performed infantry missions effectively while wearing the masks. Wearability, discomfort, malfunctions, and recommended design modifications are described. Significant changes in design features of the prototype masks were proposed as a result of observations during these trials.
