An ice chest, also known as a cooler, is a portable container designed to keep food and beverages cold. It typically features thick insulation and a tight-sealing lid to maintain low temperatures. Ice chests are commonly used for picnics, camping trips, and outdoor events, allowing people to enjoy perishable items without refrigeration. These containers can be made from various materials, including plastic and metal, and come in different sizes. Some ice chests are equipped with wheels and handles for easy transport. They are often used in conjunction with ice packs or ice cubes to enhance cooling efficiency, making them a popular choice for outdoor activities.
