Geigerrig Rig 500 70oz., $130.00
Features: This vest is purely focused on hydration, with the most innovative bladder that any of our testers have seen. One of the biggest problems with bladders is the issue of having to drink with a lot of effort. With its unique pressurized system, all you have to do with this vest is swallow. Excellent features of being able to turn the bladder inside out and place it in the dishwasher and the ability to attach two types of in-line filters to refill the bladder from anywhere made this the most popular system of any vest tested.
Cons: The pack, although really comfortable with excellent construction, was too heavy and bulky for trail running. They have many different styles but the Rig Cadence looks to be the best option for runners.
