    Osprey Hydraulics Reservoir - 3 Liter is rated 3.4118 out of 5 by 17.
    Rated 5 out of 5 by from Good For Me!!! Finally got to used this water reservoir this weekend and it was perfect!I hike with a Osprey Atmos 65 and would use your typical 16oz Arrowhead/Smartwater container placed in the external side pockets with with a Platypus soft battle as a reserve placed in my pack. It may be just me, but I could NEVER retrieve or replace the bottles from the side pockets without any assistance while hiking. With the 3L bladder I'm able to drink whenever I want with NO problem at all! The design is a bit bigger than others with the same capacity, but still fits snug in your pack. To give a better prospective, my son has the same pack but uses a 3L Blackhawk water reservoir. While I'm able to tuck my reservoir securely in the pack, he on the other-hand, has to place all the items in his pack and then lay the reservoir on top. This is because his fills up like a fat balloon, where the Osprey is designed to spread load the shape and keeping it a somewhat slender shape. The other thing I notice is my son also has a difficult time filling the reservoir, but the handle on the Osprey allows EASY filing. The only con to this product is the weight. It is by no means heavy at all, but if you are someone who is really concerned about the weight of their gear then you have to make that choice. All-in-all I am super pleased and not going back to the 16oz bottles. Hope this helps -Happy Trails (Note: I do keep an empty 16oz bottle for mixing drinks)

    Rated 1 out of 5 by from No good for 2012 and prior This 2013 model does not have a plastic panel on the back like the 2012 model and prior did. As a result, the bladder bulges the pack and it does not conform to wearer's back. And it causes the pack to roll and it's uncomfortable. Maybe 2013 model year packs have the conforming panel in theirselves. But my 2011 model Raptor 10 doesn't. The reservoir does. I ordered 2012 model reservoirs at REI Outlet, and returning my 2013 model.

    Rated 1 out of 5 by from disappointing My significant other and I both purchased this bladder to go with our new Osprey packs for a multi-day backpacking trip. We made the mistake of not testing the bladders before we left for the trek. My bladder ended up having a leak near its base and was totally unusable. My boyfriend's leaked at the nozzle whenever it was turned to the "on" position. I really regretted not bringing my old trusty Camelbak! We trusted the Osprey brand from previous purchases, which is why we didn't test drive these bladders. I definitely learned my lesson there.

    Rated 4 out of 5 by from yay! The thing that sold me with this one was the magnetic clip-on, which i lost a few days after buying it. I used this at coachella for the first time and it was great! I also have used it before for day hiking, as i put in in my osprey pack. it is not hard to refill, but you have to adjust at an angle, which can become annoying.

    Rated 5 out of 5 by from One of the best hydration packs I bought this not long after I picked up a Osprey Aether pack. my first use was a day hike and my next use was a summit of Rainier. This was one of the best products I have ever owned. The magnetic attachment to my chest strap gave me quick access and kept it out of the way during some more technical climbs. The quick 90 degree switch can be turned on and off with ease and no leakage down my gear. I love how easy it was to hydrate and how ergonomically designed the product is to fit so well with my Osprey pack. My other hydration pack felt so bulky while in my pack against my back. This upgrade was an easy choice and the best choice I made in regards to comfort and capacity. Cleaning is easy as it is easy to disassemble. I have the 3 litre version and so glad I went bigger. Great job Osprey.

    Rated 5 out of 5 by from OspreyHydraulics Replacement Works Great I was afraid this product might not work for me at first because it looked very different than the one I was replacing, but it works great.

    Rated 4 out of 5 by from 3 liter bladder First, Osprey makes a great product. And I would recommed Osprey to anyone. On a recent mountain bike ride I fell onto my back rupturing the bladder. Instead of it failing at points which you would think would be obvious, seams, filler cap, drinking tube, it burst just above the filler cap. I purchased this one to replace it. My pack is a 2012 Viper 10 with a 100oz/3 liter bladder. This new redesigned bladder does not fit into my pack. It is too big. So if you have an older Osprey you might want to try to source one of the old style bladders.

    Rated 5 out of 5 by from great hydration pack! Actually, I own 3 of these hydration packs. They are easy to fill, easy to dry out, and very durable. I use the 2L for snowboarding and it's almost 4 years old now. I bought the 3L for Mount Whitney and it performed great. No complaints.
