Nothing but items to purify and transport your water so you can stay hydrated! For starters, we included two carry storage systems that can hold over five and a half gallons. To enhance that water, we added f2o waterdrop packs in order to replenish electrolytes and other important nutrients. With the BattlBox camp bottle set and bail, you can store water and also have the ability to hang the bottle to boil water for drinking or cooking. Finally, we included a purifying drinking straw and two flasks to store whatever liquids you may desire.
