Maybe someone needs to come up with an attachment for a water bottle or bladder to "hose" yourself off with. Something that detachs so it can be put away or even a light, separate bladder with a simple way to pressurize it so you can hit the right spot. Could even be hung around your neck to use elevation to create some pressure, but a longer hose then what comes with a bladder may be needed. Don't have time to grab mine to check its length.
