The insulation performance of a waterproof soft cooler can vary depending on the specific product and its design. However, these bags are typically designed to provide good thermal insulation. They are equipped with insulating materials and a sealed, waterproof lining to help maintain the temperature of food and beverages.
The duration for which a waterproof soft cooler can maintain the temperature of its contents depends on factors such as the initial temperature of the items stored, the external temperature, and the quality of the bag. In general, these bags can keep food and beverages cool for several hours, often ranging from 4 to 24 hours, or even longer in some cases. Some high-quality models are capable of maintaining temperature for an entire day or more.
