Unlike gravity camp showers that need to be hung overhead and produce dismal water pressure, Helio LX rests securely on the ground and delivers 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 voluminous 5.8-gallon tank with a foot pump and with occasional pumps you can keep it fully pressurized for 710 minutes of strong, continuous spray. The tank cannot be over-inflated. 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.
