Hydrating from a hydration pack should be easy and continuous, not hurried and gluttonous.

Users of the GEIGERRIG hydration packs during activity report that they comfortably drink 30% more water than they do when using standard, un-pressurized, sucking hydration packs.
With GEIGERRIG Hydration Packs, all that you'll need to do is lightly bite down.
The GEIGERRIG pressurized system does the rest – continuous, easy, comfortable hydration without disruption or inconvenient sucking.

During strenuous activities, it can be inconvenient to suck on the bite valves of traditional hydration packs, to access and hold a water bottle, or to otherwise drink.
Subsequently :
We do not hydrate sufficiently or  at all because it is inconvenient to carry water.
Stopping to drink when we would prefer to continue our activity.
And/or hurriedly taking large gulps of water whenever we feel absolutely forced to by extreme thirst.

GEIGERRIG, pressurized hydration packs spray the water into your mouth with no more effort than a quick pinch of the bite valve or a light bite with your teeth. 
Convenient, easy, comfortable and cleaner...NEVER SUCK AGAIN!
