Abstract: An evaporative cooling device including a combination of insulative surfaces and evaporative surfaces that may hold and cool contents with walls that are made of semipermeable materials. The evaporative surfaces store and facilitate the evaporation of a liquid to cool the interior of the evaporative cooling device while the insulative surfaces limit heat transfer in or out of the evaporative cooling device from air, sunlight or the ground. The evaporative cooling device is further capable of holding a variety of products at a temperature below ambient environmental temperature, assuming less than 100% humidity. Moreover, the evaporative cooling device may be designed to be lightweight and collapsible for easy transport and storage.
