The award-winning pressurized GEIGERRIG Hydration System allows you to spray water to hydrate, share, clean, cool, etc.--anything you need. The pressurization enables convenient in-line plug-and-play filtration for on-the-go access to natural fresh water sources. When you are done, simply flip your Hydration Engine inside out and place it on the top shelf of the dishwasher for easy cleaning and drying. The Tactical 1600 is a 1600 cubic inch pack built to military specifications to keep you hydrated AND carry all of your gear. Attach a sleeping pad with the bed roll straps, stabilize your gear using the compression straps, and carry heavy loads easily with the load bearing waist belt. The biggest, baddest pack in the Geigerrig arsenal.
