The easiest way to stay fresh is to use a suspended water container.
Made from durable, leak-free fabric, they’re usually fitted with a basic shower nozzle and suspension cords. You simply fill the container with water, hang it from a point high enough for you to stand comfortably underneath and turn on the tap.
Your shower may be cold but the nozzle enables you to use clean water without excessive wastage.
Tip:
Take along additional rope/cord for high tree branches. Your shower should hang close to your head to optimise water pressure.
