Is cotton an appropriate material for SAR providers to wear?

Cotton is generally not an appropriate material for Search and Rescue providers to wear, particularly in high-stakes or outdoor environments. The primary reason for this is that cotton absorbs moisture and retains it. When SAR personnel are in wet conditions, whether from rain, sweat, or water rescues, wet cotton can lead to a rapid loss of body heat, increasing the risk of hypothermia.

In contrast, synthetic fabrics and wool are preferred because they wick moisture away from the body, keep the wearer dry, and provide insulation even when wet. Therefore, the statement that cotton is not suitable is valid and reinforces the importance of fabric choice in maintaining safety and functionality during SAR operations.
