“The 1000 ml” is addressed to solve problems occurring to refugees, people migrating in difficult conditions and victims of natural disasters. The main problem which they are struggling with are the lack of access of drinkable water and food, outdoor sleeping as well as long distance walk and carrying belongings in nonfunctional plastic bags. A backpack jacket is made of impregnated weatherproof fabric. To serve as immediate aid for those in need: offering basic outer garment, facilitated luggage-carrying and easy access to clean water. The backpack jacket is packed in a bottle which, when emptied, can be used for storing water or food or as a container to purify contaminated water (the set includes tablets to make the water fit for consumption). The set contains a backpack jacket, a bottle and a blister pack of 10 tablets.
