Frequently Asked Questions

AI
To get the most out of your bag, pre-chill the interior if possible and use high-quality gel ice packs. Minimize the number of times you open the bag to prevent cold air from escaping.
Most general-purpose isothermal bags are for food. For medication, look for specialized medical-grade bags that provide guaranteed temperature ranges for specific durations.
Avoid machine washing as it can damage the thermal lining. Instead, wipe the interior with a damp cloth and mild soap, then air dry completely to prevent mold.
