Insulated cups are specially designed containers that help maintain the temperature of beverages, keeping drinks hot or cold for extended periods. They typically feature double-walled construction, which creates a barrier that reduces heat transfer. This design is commonly used in products from brands like Thermos and YETI. These cups are popular for both everyday use and outdoor activities, as they are often made from durable materials like stainless steel or BPA-free plastic. Many insulated cups also come with lids to prevent spills and enhance portability, making them ideal for travel, work, or leisure.
