JUMA is working to revamp their hot liquids backpack that students use to sell drinks at event Stadiums. These backpacks hold 3 Gallons and when full weigh ~35 lbs. Since the current backpack is a one-size-fits-all adult model, it can be difficult and painful to use for the 16 to 24 year old students who drastically range in size. Currently the backpacks are passable, but a little bit of design engineering would vastly improve them.
To modify the hot liquids backpack to be easier and more comfortable to use for the high school students JUMA employs.
