The water-transportation-backpack, called “Fullfiller” is an easy transported bag which filtrates the water while sampling it inside. In some territories the distance between water place and village is many miles long. The “fullfiller” is able to contain 20l of water and a great alternative to clay jugs and old cans. Because of its breast and hip belts and its specific shape the weight spreads smoothly on the whole body while arms and hands are still free in its movements. Due to the integrated filter people are able to drink clean and abacterial water.
