Providing maximum levels of stability and ease of use, the Hydraulics™ reservoir is essential for keeping hydrated on your outdoor adventures. The unique combination of the pour shield and Slide-Seal™ top-opening allows you to easily fill and empty the reservoir, whilst enabling complete access for cleaning after use. Our unique Osprey Hydraulics™ anatomically shaped back plate provides stability and creates a flat profile to ensure the reservoir easily slides in and out of your pack. The bite valve is magnetic enabling easy stow and access to water on the go. When not in use the bite valve also incorporates an easy on/off twist lock system. Built from strong yet light TPU material, which is designed to withstand either freezing or hot water. The QuickConnect™ system allows you to remove the reservoir for easier loading, replacement and cleaning.
*Magnets may cause compass deviation. Always keep your compass and magnetic bite-valve separate.

Review by: ju
I used the water bag on one week walking tour and it served very well. I followed the suggestion of the manufacturer and had the bag filled with lemon water and put it in the freezer. Afterward I did not notice any plastic taste. The only comment for improvement have is the adjustment in the Osprey backpack. There is only a very short and tiny band inside the backpack to put around the handle to hold that the water bag. If the holding band would be longer and adjustable in length, one would easier fit it in.

This is an excellent product.
This is an excellent product. I bought a similar one that was cheaper, however it was highly inferior. My view is it costs more than others for a reason, and it delivers really well on simplicity to use and durability

Great addition to my walking equipment
Its a hydration bag, it does the job, fits into my osprey pack,o dd taste has gone. Once i worked out the magnet attaches to the chest strap the convenience of this became all to obvious, not much more i can say. Sure there are cheaper options around but you get what you pay for, i think its worth a few extra pounds.

Excellent water reservoir
I recently bought a 3Litre reservoir to fit my Atmos AG and its fantastic! I love the way it has its own pouch in the bag and that the tube can come through. The magnetic sternum clip is brilliant. 10/10 Would recommend.

I bought this and tested it and it does what it is supposed to do with aplomb. I then bought the insulated hose to use instead of the existing one but cannot figure out how to attach it to the bladder. The existing hose has an attachment that slots into the bladder but the insulated hose has no such attachment and the one on the existing hose does not appear removable in order to reattach to the insulated hose. Please advise. Thanks.

The best rucksack company in the world. 100%.
BISH BASH BOSH! It's all about the big bellied 3 litre bad boy bladder. The hits keep coming Osprey, I don't know if I can take any more.
HAPPY HAPPY HAPPY!
I bought an Osprey Aether AG 70l rucksack. Happy x 3. Delighted.
I bought a Daylite Plus to make my Osprey Aether 70l rucksack a 90l rucksack. Happy x 3 again. Even more delighted.
I bought an Osprey X-large Ultralight 70-100 litre+ raincover to cover my Aether 70 & Daylite plus from the rain. Happy x 3. Now the party is getting started I thought to myself. Can it possibly get any better? Oh yes, it does. the hits just keep on rolling out.
I just went out & bought the 3 litre Big Daddy water bladder to fit in my Aether 70 while my Daylite plus is attached to it & they are both covered by my X-Large Ultralight raincover with said 3 litre water bladder sitting quite comfortably in its own pocket. It does not get better than this in terms of rucksack equipment design. Perfect load carrier bar none. There is no competitor.
Amazing. Thankyou Osprey. I left a review on the X-large Ultralight raincover because it is just so good & I said not 5 stars Osprey, 10 Stars. Each item I have is a 10 & the way the rucksacks fit together & the raincover has the hipbelt sleeves & top lockstrap to keep in place whatever activity you are doing is a truly amazing piece of functional design in the sum of its parts although each individual part stands alone.
A Beyond Happy customer. You lot are the best rucksack company in the world. By a very long distance.
