Insulated trousers are specially designed pants that provide warmth and protection in cold weather. They are typically made with materials that trap heat while allowing moisture to escape, keeping the wearer comfortable. These trousers often feature additional layers of insulation, such as down or synthetic fibers, to enhance their thermal properties. Commonly used in outdoor activities like skiing, hiking, and hunting, insulated trousers come in various styles and sizes. Many models include features like adjustable waistbands, reinforced knees, and waterproof exteriors to ensure durability and functionality in harsh conditions.
