The stable and sturdy 10 L collapsible canister with a tap, carrying handle, and screw-on filling opening can be extremely space-savingly folded thanks to the strategically placed fold seam. The large filling opening allows for quick refilling of the canister. The robust carrying handle makes it easy to transport the water canister to the tent or camper. Once positioned with the tap facing down, sufficient water pressure is created for quick dispensing. The valve allows for the flow of water to be regulated as desired. The emptied canister should be dried with the screw-on opening facing down and rinsed with clean water before the next use.
