Certain substances retain thermal properties despite saturation with moisture. A prime example is wool, the fleece of sheep, which maintains a degree of insulation even when damp. This characteristic stems from the complex structure of wool fibers, creating air pockets that trap heat, minimizing heat loss due to water’s thermal conductivity.
This attribute is essential in environments where exposure to rain, snow, or immersion is likely. Historically, wool has been favored by outdoors enthusiasts, military personnel, and those living in regions with inclement weather due to its ability to mitigate hypothermia risks in wet conditions. Its persistent warmth contributes significantly to comfort and safety.
