This minimalistic designed and completely waterproof backpack can save lives. The patented double zippers prevent water from entering the backpack or air from escaping. In this way, it can act as a buoyancy aid in an emergency. Made from eco-friendly and quick-drying TPU, the backpack is also reinforced on the back with a multi-layered, bulletproof Kevlar layer. Detachable shoulder straps allow additional carrying methods, for example as hand luggage or a shoulder bag.
