Other hydration reservoirs require that you suck on a tube to get a drink; the Geigerrig reservoir can be pressurized with the included pressure bulb.

• Pressure bulb inflates a secondary compartment within the reservoir, which, as it is inflated, pushes water out through the bite valve
• As a result, you don't have to suck on anything to quench your thirst—just open your mouth and let fly
• Pressurized, 70 fl. oz. reservoir features a slide top and quick-release valves on the drinking tube
• Pressurization tube for easy refills, removal, cleaning and drying
• Ventilated and padded back panel, padded and mesh-backed shoulder straps and removable hipbelt offer comfortable carrying
• Zippered main compartment offers 500 cu. in. of storage
• Internal mesh zip pockets help organize contents
• 2 exterior zip pockets secure small essentials; headphone port enables cable routing
• Compression straps on the Geigerrig Rig 500 hydration pack let you cinch down loads for jostle-free carrying
