«SUPPLY» is a foldable and self-cooling drinking bag which consists of two pouches. The Bag is rapidly closed by an innovative closure. The inner pouch made of silicone contains the beverage. The outer pouch is made of a semipermeable membrane. The space between both pouches can be filled with water, which then evaporates over the membrane and cools the beverage (evaporation cooling).
«SUPPLY» features the same thread as PET-Bottles, allowing you to choose from a wide range of already existing caps.
The drinking bag is a space-saving and long-living lightweight.
