Insulated bottles are specially designed containers that keep beverages at their desired temperature for extended periods. They typically feature a double-wall construction, which creates a vacuum between the walls, minimizing heat transfer. This design helps maintain the temperature of hot drinks like coffee or tea and keeps cold drinks like water or juice refreshing. These bottles are often made from materials such as stainless steel or BPA-free plastic, making them durable and safe for everyday use. Many insulated bottles also come with leak-proof lids and are easy to clean, making them a popular choice for outdoor activities, travel, and daily hydration.
