Can be used with any backpack!

The Dual Chamber reservoir has several key components that provide key benefits for any hydration pack user:

Slide Top and Wide Mouth:

The slide top allows the entire top of the reservoir to open up to provide easy access for cleaning, drying and filling. Dishwasher Safe – turn inside out and load in the top shelf of the dishwasher for cleaning.

Pressure Bulb

The pressure bulb and pressure tube provides the mechanism to pressurize our hydration packs utilizing the Patent pend. two chamber system. While it is not always necessary to energize your hydration pack for the purposes of: Spray to drink, Spray to Cool, Spray to Clean, Spray to Share…etc. It is certainly convenient to have this capability so that you can enjoy these benefits from the hydration pack on your back.

Surge Protector Valve

The bite valve has an on-off switch as well as a special configuration that makes it uniquely suitable for pressurized, spray hydration without leakage. - This Surge Protector valve is a great product benefit that comes from our healthy relationship with the company Hydrapak.

Quick Release Valves

Unthreading the pressure tube and drinking tube from your hydration pack every time you want to refill or clean your hydration engine is inconvenient. The quick release valves allow you to easily disconnect the tubes and leave them positioned in the hydration pack while you remove the reservoir for filling and cleaning.

Plug and Play Adaptors:

Easy to detach pressurization tube and drinking tube for cleaning and refilling.

Material : #15 Denier Polyurethane

This is a tougher polyurethane that minimizes any ballooning affect that may occur when the reservoir is pressurized for spraying. GEIGERRIG Pressurized Hydration Packs have a top quality Hydration Engine. Phthalate free. BPA free. PVC free.

Compression Backing Nylon

This Nylon backing helps protect the reservoir as well as prevent any ballooning effect on the air side of the Patent pend. pressurized Ogwa bladder. Our hydration packs contain nylon sleeves that host the hydration engine, but the nylon backing on our hydration engines help slip the hydration engine into and out of our hydration packs while also providing additional protection from items that may be packed in your pressurized hydration pack.
