Rig 500 Hydration Pack Product Details 500 Cubic Inches of highly durable, ballistic pack capacity. Reversible, dishwasher safe, pressurized hydration reservoir. Filter Ready. 70 Oz. The simple spray action of the Geigerrig hydration system enables the water to be sprayed for cooling, cleaning, and sharing. The spray action of Geigerrig also enables the use of a Geigerrig plug-n-play, in-line water filter for on-the-go filtration of water found along the trail. Simply refill from a river, stream, lake or pond; pressurize the reservoir; and then plug in the small, lightweight Geigerrig filter. Now you can safely drink the crisp, cold stream water. No longer do you have to worry about running out of water. Carry less water; use the water as you need for cooling, cleaning and sharing; and refill more often from water found along the trail. At the end of the day, simply turn the reservoir inside out to clean it and to dry it. Reservoir is dishwasher safe, top shelf.
