The new generation Self-Contained Toxic-Environment Protective Outfit was tested in its two configurations, one with a backpack rebreather-respirator and a liquid-cooling vest STEPO-R, and one tethered to an air supply providing cooling and breathing air STEP-T. Also tested was the currently fielded Toxic Agent Protective TAP Suit. Six soldiers volunteered to be evaluated during exercise and rest in 27 C, 38C, and 49C environments while wearing the protective systems. The STEPO-T allowed the longest endurance time, while STEP-R reduced endurance and increased physiological strain relative to the other systems.
