Osprey Hydraulics 3L Water Reservoir

Its good. They're all expensive. I needed another one so I bought one

There are numerous people in my life that have now converted to this bladder. It's the best on the market and you can't beat their warranty!

THis was a present . I have one . Works really well

I did not want to buy an Osprey reservoir because I had been so satisfied with another major brand of reservoir that I had used for 15 years. In 2018 my old reservoir started leaking and had to be replaced. I bought and returned three reservoirs that had major leaks as soon as I filled them up. I then decided to switch to Osprey and I am glad that I did. The design is excellent. I especially like the quick disconnects that make it easy to attach directly to a filter. The closure at the top is easy to open, easy to fill, and does not leak when closed.

I have had this hydration bladder/pack for several seasons -- it replaced an older Osprey model that needed a new mouthpiece that was no longer available. I have used it for numerous day hikes and one two-night backpacking trip, and I love it. The bladder holds enough water for hot humid conditions or long outings, is easy to fill at my kitchen sink, and the water doesn't taste bad at the end of the day. The stiff back is an asset and it fits well in my 24L day pack (by another manufacturer).

Love it. Perfect for my osprey bag. And really easy to use .

I've used this bladder on hiking and backpacking trips. The high volume has been great hiking in Southern utah in 100 degree heat with wind. I've used it for short and long trails. It keeps it's shape and the back panel keeps it from sloshing around and bulging the pack to help it be more comfortable to carry so much water. It has a high flow rate which is very nice. The first time or two it had that new bladder taste, but after I cleaned it and used it more it has gone away, so I'm not sure why the other reviews are saying it's bad. The magnet clip for the sternum strap is also amazing. I'll definitely buy again in the future.

I have a small osprey day pack that I put this 3L reservoir in. Fits great and works very well. Seem to be very durable and with the extra protection on the back of it is a great idea. One tip go over the max fill line as mine leaked everywhere on the counter went it was laying flat.
