Filling up your RinseKit at home to clean the dog or wash your car is easy with a sink or hose, and you can use the Field Fill Kit when you're camping and there isn't a faucet in sight. Just fill the bag in a nearby stream or lake and take it to where you set up the RinseKit. Combined with a bike pump, the pressure adapter pushes water out of the bag and into the RinseKit to ready you for showers by the campsite.
