The Effect of Cold Protective Clothing on Comfort and Perception of Performance

Jussila K., Valkama A., Remes J., Anttonen H., Peitso A.

International Journal of Occupational Safety and Ergonomics

2010

Vol. 16, No. 2

185--197

The physiological properties of clothing designed to provide protection against cold, windy and damp conditions affect comfort. The weight, thickness, stiffness of the fabrics and friction between the clothing layers affect physical performance. The comfort and perception of performance associated with 3 military winter combat clothing systems from different decades (the new M05 system, the previous M91 system and traditional clothing) were observed during a winter military manoeuvre. Subjective experiences concerning comfort and performance were recorded for 319 subjects using questionnaires. The most challenging conditions for comfort and performance were perspiration in the cold and external moisture. The new M05 system provided warmer thermal sensations (p < .010), dryer moisture sensations in the presence of external dampness (p < .001), dryer perspiration moisture sensations (p < .050) and better perception of physical (p < .001) and mental performance (p < .001) than the other systems. Careful development of the clothing system guarantees good comfort and performance during cold exposure.
