    Osprey Hydraulics Reservoir - 2 Literis rated3.4286out of5by7.
    Rated4out of5byfromBetter then a spineless bagFits well with the brand line of packs. If you don't have a restraining strap to keep the pouch from slumping in your pack the built in handle does a pretty good job. The handle also does a great job of keeping the pouch open when filling from a faucet. A very nice design. The bite valve is drip free and the ability to rotate the valve to prevent accidental discharge is great for when the gear is piled in the back of the truck. Beware that Ravens seem to be attracted to the bite valve. We hung our packs in a tree while we did a short side hike and came back to a decimated valve and tube. Never had that happen with any other brand. The unit is on the heavy side.

    Rated1out of5byfromDisappointed by cross threading problemThe commment below matches my experience. I had a soaked backpack two days in a row because the cap seemed to be on securely, but was actually cross threaded. When you are exhausted, camping at night with minimal lighting, doing alpine starts, is not the time to have any concerns about your water supply. There are plenty of other things to think about and be concerned about. Compared to the previous Osprey model this one is abysmally deficient and was a huge disappointment. I returned it to REI after my 7 day trip in Colorado. Also, a word about the 'cap': I and a friend of mine just got Osprey packs back in March, 2013 (I got the Raven 14 & he got the Raptor 14), absolutely love theses packs...the best...but now the caps keep wanting to cross-thread, where the cap itself, and the plastic "hinge" that holds to the pack makes turning the cap difficult. You end up having to try to balance holding the 'hinge', trying to turn the cap 'just so', and trying not to spill water everywhere, even my friend has a bit of a 'struggle to get the caps to tighten down correctly. I recently read on the Osprey Raptor section of another customer complaining about the same exact thing. These were not left in a hot car, nor any hot water inside them where the plastic could have been warped somehow. It's just poor threading on lid and collar. May not be a problem with all, maybe just a bad-run from the factory. Just be aware that this may be a problem. (this is for the 2013 models). I have contacted Osprey and waiting for a response. May return to B.C., but hate to do without my pa ck! *So, if you experience this problem with yours, try holding the plastic hinge that connects the cap to the collar, and then turn the helps.

    Rated4out of5byfromCamino companionUsed it for a 100+ km hike on the Camino de Santiago in 80+ degree weather. Covered up to 30 kms per day. Couldn't have done it without the Osprey. This was the first time we ever used anything like this. Looking forward to taking it along on future day hikes and trips.

    Rated1out of5byfromPoor and Frustrating ConstructionFor all the great packs they make, Osprey cannot seem to get the hydration systems right. This is my second Osprey 2 liter hydration bladder. The first began to leak at the seams within the second use. I bought the updated version and while the construction is better (no more seams along the top to leak), they managed to construct a filler cap that is almost impossible to screw on securely. While this may not be an issue if you are filling in your kitchen and have lots of patience, it is a real issue if you are in the back country and trying to fill your bladder in the rain or in a hurry. While not as "feature friendly", I recommend the MSR Dromedary. Simple, solid construction and very reliable.

    Rated4out of5byfromLove the magnet.I use this for backpacking/hiking. The magnet sternum strap is the selling point for me. Works well with my Gregory backpack. The stiffness makes it easy to slide in and out. The non-detachable tube and rigid plastic make it a bit more difficult to clean and refill though.

    Rated5out of5byfromDrink up!This is a re-working of the old Nalgene hydration bladder. They have solved one of the main issues with the old Nalgene, which was leakage from the hose/bladder connection. The bladder material is good and solid, and I would expect it to last a long time. I love the bite valve on this, which is one of the reasons I decided on the Osprey. It fits easily into my daypack and overnight pack... the rigid frame and handle make it easy to get in and out of the pack, which is one of my major complaints about these things. Very nicely made... may be a tad heavy for some, but it helps me to stay hydrated during long days on the trail.

    Rated5out of5byfromBest water bladderI field tested this water bladder on a three day two night camping trip and loved it. The shoulder magnet made it very easy to access then just clip right back. The only issue I had was that we were using a MSR filer and the mouth of the water bladder is wider than the filter. However a friend of mine mentioned bringin along a nalgene, filtering the water into the nalgene and pouring the water into the bladder.
