Why is it important to wear layers in cold weather?

Wearing layers in cold weather is essential primarily for insulation and moisture management. The layered approach offers several advantages that enhance comfort and safety in low temperatures.

By wearing multiple layers, you can create air pockets between the layers that effectively trap heat generated by your body, which acts as insulation against cold air. The base layer is designed to wick moisture away from your skin, keeping you dry; this is crucial because moisture can lead to heat loss and make you feel much colder. The middle layer serves as insulation, while the outer layer protects against wind and moisture from the environment. This combination allows for better temperature regulation, helping you stay warm without overheating during physical activity.

The other options do not address the physiological needs for warmth and moisture control essential in cold weather, emphasizing why the insulation and moisture management benefit of layering is paramount.
