Which material is recommended for extra clothing in cold weather?

The recommended material for extra clothing in cold weather is polyester. This synthetic fabric has excellent insulating properties, which help to retain body heat while also allowing moisture to escape, keeping you dry and warm. Polyester is lightweight, durable, and resistant to shrinking and wrinkling, making it a practical choice for insulating layers in colder conditions.

When considering other materials, cotton tends to absorb moisture and can retain it, which might make a person feel colder once they start to sweat or if they encounter any moisture. Silk, while it has some insulating properties, is not as effective as polyester for maintaining warmth in cold conditions, and denim is heavy and not suitable for layering due to its rigidity and moisture retention capabilities. Therefore, polyester stands out as the superior choice for cold-weather clothing.
