Abstract: Appropriate clothing is important for maintaining operative capability during cold weather operations. This study examined the impact of different cold weather combat uniforms on body temperature, manual performance, comfort and perspiration among nine male soldiers (aged 24 ± 4 years) in field conditions (-2 to 5 °C). They completed three trials, consisting of a 1-h walk at 5 km/h and 1 h passive standing, wearing uniforms with varying insulation levels (1.9, 2.2 and 2.5 Clo). The results show that uniform type and insulation significantly affect skin temperature, moisture accumulation and manual dexterity in mild sub-Arctic winter conditions. Results also indicate that the insulation and design of hand protection significantly influence hand and finger skin temperatures, which in turn affects manual performance, independent of overall clothing insulation. Finally, while models like required clothing insulation (IREQ) are useful for initial recommendations, individual adjustments are needed to maintain comfort and prevent cold weather injuries.
