Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The subjects will undergo 5 experiment days: Recruitment day, one day of acclimatization to heat, and 3 days of performing experiment protocol, each day dressed with different protective garment (Protective garment in current use + NBC mask, new BC protective undergarment + standard combat uniforms, new BC protective undergarment + standard combat uniforms + NBC mask).
Core (rectal) and skin temperature and heart rate will be monitored continuously, liquid balance will be recorded.the physiological heat strain will be assessed and compared between the different protective garments.

Research arm
10 young and healthy civilian volunteers will participate in this study. The subjects will undergo 5 experiment days:
1. Recruitment , medical examination and VO2max test.
2. Acclimatization day by performing moderate exercise protocol under hot and humid climate.
3. 3 days of performing moderate exercise under hot and humid conditions protocol, each day dressed with different protective garment:
1. Protective garment in current use + NBC mask.
2. The new BC protective undergarment + standard combat uniforms
3. The new BC protective undergarment + standard combat uniforms + NBC mask
exercise under hot and humid conditions protocol
acclimatization day protocol: 2 hour effort performed in a climatic chamber, which include walk on a treadmill at 5 Km/h on a 2% incline under heat conditions (40 deg. centigrade \& 40% RH) Core (rectal) and skin temperature and heart rate will be monitored continuously
experiment days (3 days): 2 hour effort (2 cycles of: 50 min walk and 10 min rest-sitting) performed in a climatic chamber, which include walk on a treadmill at 5 Km/h on a 2% incline under heat conditions (30 deg. centigrade \& 60% RH) Core (rectal) and skin temperature and heart rate will be monitored continuously.
