Last Summer I received the GeigerRig Rig 1600 backpack for review as part of the Hydration Summit, sponsored by Trail Sherpa and GeigerRig.  The Hydration Summit featured 15 high-profile outdoor bloggers discussing a wide variety of hydration topics from waterborne illness to keeping your kids hydrated on the trail.  GeigerRig challenged us to do side-by-side comparisons between their new Hydration Engine and the other leading hydration pack manufacturers.  My focus at the time was on the bladder and comparing it to the other leading brands on the market.  Thus, I never got a chance to write a review of the pack itself.  Now that I’ve had the pack for a while and put it through it’s paces, I thought it was time to let you guys know what I think.

GeigerRig: The Hydration Engine…

The whole thing centers around what GeigerRig calls, the Hydration Engine.  It is a pressurized reservoir system that allows the user to spray fluid from the drinking hose instead of using suction.  Pressurizing the system allows you to work with a stream of water.  In Katie’s review of the Rig 500, she finds, “…the pressurization feature most useful when mountain biking; drinking while pedaling uphill and breathing hard was much easier than trying to suck out of a normal drink tube.”

What I really like about the design of the reservoir is the closure design.  It’s a very simple fold-over clip design but it allows the entire top of the bladder to open making it incredibly easy to fill anywhere.  It also allows the bladder to be turned inside out for cleaning.  GeigerRig recommends turning the reservoir inside-out and placing it on the top rack of your dish washer.  No more trying to use pipe-cleaners and annoying brushes to clean the bladder because you can’t get your hand through the opening.

“People who use GEIGERRIG hydration packs during activity report that they comfortably drink 30% more water than they do when using standard, un-pressurized, sucking hydration packs.” –


The most impressive part of the GeigerRig reservoir is it’s durability.  The thing is damn near indestructible.  When I did my initial testing I put all my weight on the bladder and it didn’t flinch.  Bob Geiger produced a video of them testing the reservoirs for their breaking point and finally got one to pop at over 1,100 PSI.  You might also like this video of GeigerRig trying to blow up a Rig 700.


GeigerRig: The Backpacks…

GeigerRig Rig 1600 gear testing in the desertGeigerRig started developing their products to be used by the military in combat situations.  All of their Rigs are made from industrial strength Ballistic Nylon. They are put together using heavy duty zippers and redundant stitching.  The buckles and clasps are high-grade polymer plastics made to take tons of abuse.  They’re also made to carry some serious weight and the padding on the shoulder straps is beefy enough to do so comfortably.


“We felt that [Ballistic Nylon] was perfect for our RIGS as we wanted to have hydration packs in our line-up that could take heavy abuse delivered by hard core outdoor enthusiasts and motor sports enthusiasts.”

I also have the Rig 500 and it’s made with the same heavy-duty construction of it’s big brother.  The Rig 500 is smaller and more streamlined, designed more for mountain biking or trail running.  It will fit the 3L reservoir but is designed more for the 2L.  The storage capacity is obviously much tighter than the Rig 1600 but there is still room for snacks, first aid and a spare shirt or extra layer.

The Bottom Line

These are heavy packs, and made to take a ton of abuse.  If you're one of those people that's hard on gear and expect it to take a beating, you'll be happy with GeigerRig.  The Rig 1600 is comfortable and carries a ton of gear.  I use it all the time for day hikes and regularly stuff it with rain clothes, my hammock, snacks, my DSLR and lenses and have room to spare.  I took it to Costa Rica and my wife and I were able to pack everything we needed for both us for an entire day in that pack without trouble.


The Rig 700 is a nice biking pack.  It's a little too heavy for me as a trail running pack, and doesn't fit me quite as well as the Rig 1600 but it's still a nice, well made pack.


All of GeigerRig's Hydration Engine's carry a lifetime warranty against leakage.

  1. Just got a new Rig 1600 for a hike up Mt. Fuji. Wondered if you could suggest how I could use the belt pockets that are OUTSIDE of the zipper and under the 2 elastic vertical bands. I can’t figure out how these horizontal small (4 fingers width) pockets can be used… or why they were designed. Perhaps the design is made only to ventilate or expand these belt zipper pockets, and not for pocketing… I just want to be make the most of my new GeigerRig.

    • Val,

      I think those are just part of the pockets on the hip belt. The pockets are made of a very stretchy material so you can stuff them with whatever you want.
