Geigerrig Pressurized Hydration Engine and Reservoir;

Ditch the traditional hydration reservoir for the Geigerrig pressurized hydration engine. Simply add pressure to your reservoir using the power bulb and have on-demand water that sprays. Reversible, dishwasher safe design makes cleaning it extremely simple. All Geigerrig engines are covered by a lifetime warranty against leaks for years and years of use. Remove the slide top and easily refill from any river, stream, lake, or pond. Protect your thirst by plugging an Aquamira Frontier Filter inline via the built in quick connects and have a complete hydration and filtration system anywhere you go. The 3 Liter (100 oz.) engine fits the RIG and all larger hydration packs, including your existing pack.
