This is an easy way of carrying water on a long hile. It seems well made though tastes a little of the new plastic. I expect that will disappear with a few uses.

I had the previous screw cap Osprey reservoir and had no end of problems with it, it leaked constantly, wouldn't shut and caused so much frustration.
I was a bit reticent to get another Osprey reservoir, but the reviews were great and I'm very impressed with my Osprey rucksack so I did, and i'm so glad!
The reservoir is great, easy to fill, empty, and clean, no leakage problems and makes hiking with a reservoir a real pleasure.

Bought this for some long hikes in Greece this year on the advice of someone who told me that a water bladder makes life a bit easier on long walks. I was a bit wary of the slide lock system as it seemed a bit weird but found it did indeed make filling, emptying and cleaning easy and so far it hasn’t leaked a bit. You need to read the instructions on this as getting working for the first time is a bit weird – fresh from the box it was hard to figure out without a read of the instructions !!! I went for the 2 Litre bladder as that’s the max my Talon 11 can take and found that about right for the walks I was taking – I tended to carry a few spare bottles of water as well for rest stops.
The bladder made the water taste a bit plasticky at first but after some diluted orange juice was used the plastic taste seemed to go away after a couple of refills. I did try adding some lemon juice to take the plastic taste out but it didn’t seem to work too well. The orange cordial solved the taste issue after a few refills.
The magnetic clip and harness attachment with it was really useful as well and kept the mouthpiece in a good position. I found it a real help as I do tend to get a bit reluctant to stop for breaks when walking and can end up pretty dehydrated. Being able to just take a few sips without having to mess about with water bottles made life a lot easier.
Great bit of kit and I was well pleased with the way it worked and it fitted into the Talon II perfectly making carrying water a lot easier and more comfortable and freeing up bag space for other items.

Wish they had included a cover for the mouthpiece for when you take the pack off as otherwise it tends to dangle on the floor – I just bought some extra harness magnetic attachments to put on the Talon pack load lifter straps so when I take the pack off I can clip the mouthpiece to the load lifter straps and keep it off the deck. It’s a minor quibble and few bits of kit are ever perfect – this is as good as I need it to be.

Worked great and I would buy another if I needed to replace it.
