Why We Like The Gregory 3D Hydro 3L Reservoir
The Gregory 3D Hydro 3L Reservoir is built to be easy to clean and easy to fill, with all the adaptability we need for our biggest adventures. The Hydro is constructed with a soft-molded 3D shape that's self-supporting and prevents the bottom and top layers from folding in on themselves, which promotes a faster dry time and limits bacterial growth. A full-length baffle along the interior of the bladder discourages the reservoir from sloshing around as we hike or bike. Meanwhile, the crescent-shaped handgrip makes for an easy, spill-free filling experience, and the QuickDry Hanger provides effortless storage and drying once we're done for the day.

I’ve used this on a back country hiking trip. Love the handle, a lot easier to use versus some other brands. Thank you Gregory for keeping it simple:)

Ingenious reservoir
Great design, easily removed from my backpack for filling and cleaning, superior to my Camelback that I have used in the past.

Highly recommended hydration pack!
First use for me of the Gregory hydration pack was a 4-day backpacking trip in the Grand Canyon. Big fan of this hydration pack. Quick disconnect made it easy to refill without having to remove items out of my pack (was using an Osprey Atmos 65 pack). Handle on the front of the hydration pack and the 3-D shape gives the pack excellent rigidity and makes it even easier to handle. Only “issue” I had was using the Gregory hydration pack with an Osprey backpack. Hanging the hydration pack from the hydration hook within the Osprey back pack caused the water tube from the hydration pack to fold slightly right before it exits the backpack. This didn’t restrict the flow of water but I decided not to use hydration hook in the Osprey backpack 3 out of the 4-days of my trip and didn’t have any problems with the Gregory hydration pack freely floating in the backpacks designated hydration sleeve. All that said, I would definitely recommend this to anyone looking for a hydration pack.

Favorite bladder for any pack
This is far and away my favorite bladder. I bought a Gregory Nano 18 H20 just because of the bladder. It’s best feature are: - detachable tube so you can refill the reservoir without having to reroute the tube - wide mouth - carrying handle - flat back It’s great for any use. Whichever pack I bring hiking or backpacking, I always use this bladder. Note: I bought a 3rd party magnetic clasp for when I use it with other packs.

Kudos
This reservoir is perfect for any hike, cleaning couldn’t be any easier, I especially like the design of detachable hose and simple close valve to prevent leakage. Kudos to those who designed something so simple but exceptionally practical!!

Bite valve opening should be open from the factory
Love the reservoir and it’s excellent fit in the pack. One issue - it was very difficult to get the water flowing through bite valve. After much massaging and working with it, the slit finally opened. Now it is awesome.

I just used this fresh out of the box at Isle Royale National Park & after 27 years of backpacking, this reservoir was a game changer!!

Good bladder
Good bladder - easy to fill and place within a Gregory pack. The bite valve doesn’t have as much give as others I have used but still works well.

Can you put hot water in this to use as a hot water bottle at night?

Can you give the size of the O-ring that seals the hose connection to the reservoir for the 3L size? I lost the O-ring and cannot find the dimensions to purchase a replacement. Love this product and want to keep using it! Thanks

How do I get the plastic taste out of the reservoir. I took it on a week hike in the Alos in Switzerland and could not drink the water it tasted horrible and I cleaned it appropriately before use. Thank you.

How do you get the water flowing the first time. It won't come out. What am I missing?

Is there any difference between these 3D reservoirs and the original 3D reservoirs?
