Geigerrig offers some of the best new hydration technology in the Rig 500 2 Liter Hydration Pack that's equipped with the Hydration Engine Reservoir- a patented, pressurized system that provides continuous, easy, comfortable hydration without disruption or inconvenient sucking. The pressurized technology allows a constant spray of water into your mouth with no more effort than a quick pinch of the bite valve or a light bite with your teeth. The pressure is applied on the water bladder by a separate air chamber that you fill via a shoulder-strap pump. Use the valve to spray your face, clean a wound, even shower. It's great for a long run, hike or mountain bike tour when you're just too tired to suck on a bite valve. Continuous, easy, comfortable hydration! The slide top allows the entire top of the reservoir to open up to provide easy access for cleaning, drying and filling. Quick-release valves for drinking tube and pressurization tube allow for easy refill and bladder removal as well as a slide top for easy refill, cleaning and drying. Reservoir is dishwasher safe. Ventilated and padded back panel, padded and mesh-backed shoulder straps and adjustable hipbelt for comfortable carrying.
