The travel bottle shower fits all narrow neck water bottles to create a pocket size shower. It can be used while camping or even to wash your hands and feet on the beach. The individual shower heads simply twist into the top and when the bottle is upturned, produces a constant pumped shower flow. No squeezing is required. 2 litre bottle yields a 2 minute 24 second shower, comes with a hanging cord and a Loc-Top bag for storage.
