The Rig is designed primarily as a lean, mean water carrying pack with some additional space for a few small items. This Geigerrig includes a 70 oz. engine to keep you hydrated and will accept a 100 oz. engine (sold separately). The pack is made from heavy duty 840 ballistic nylon and includes shoulder straps, chest strap and waist strap. The Rig is built for comfort on the go with mesh covered waffle padding and magnetic tube holder.
The Geigerrig represents the next big leap in portable hydration system performance! There are many differences, but the pivotal difference is in how your liquid is delivered. Traditional hydration packs require the user to suck to drink water, but the Geigerrig utilizes a simple, yet brilliant pressurized set-up that sprays the water. The only effort required to get a drink is lightly pinching the bite valve with your fingers or teeth. It's a seemingly small difference until you consider how much more your hydration pack can do for you.
The core of the the Geigerrig is the Hydration Engine, which is a 2-chamber bladder of reservoir; one chamber is filled with your water or liquid while the other chamber is pressurized with air using the Power Bulb, which also has a depressurization button. The Geigerrig has simple, reliable quick-release valves to quickly disconnect you tubes from the Engine (bladder). The Geigerrig bladder has a wide-mouth opening and slide top closure. Another impressive feature of the Hydration Engine is that it's reversible (for drying out) and it's also dishwasher safe!
