Unlike gravity camp showers that need to be hung overhead and produce dismal water pressure, the award-winning Helio portable pressurized shower and sprayer rests on the ground and provides the pressure you need to wash hair, do the dishes, rinse off gear, water your plants, or wash the dog. You can quickly and easily pressurize the 2.9-gallon tank with a foot pump - and with occasional pumps you can keep it fully pressurized for 5-7 minutes of strong, continuous spray. The tank cannot be over-inflated. Set the black tank in the sun to warm up gradually, or fill it directly with hot water for a warm shower.Refill Helio anywhere, even without a hose. The 7-foot neoprene hose is long enough to hold it overhead for a shower, or to reach all angles of dirty gear, muddy paws, or salty wetsuits. Pair with Heliopolis privacy shelter, which has a fitted nozzle holder for hands-free overhead showering, for the ultimate home-away-from-home shower in the backcountry.
