I've been using a 2.5L for day hiking where water is scarce as well as long backpacking adventures. Unfortunately it recently developed a crack in lower 90 degree hose attachment part. I'm sure I caused fatigue to it somehow as it got heavy use. I really like the ability to connect the filter pump to the bladder without removing it from the backpack. Since I used it hard and put many miles on it in the past three years, I'm due for another one. After looking at the choices I've decided I'm purchasing the Osprey 2.5 again. I really like the design and the material they use. It seems to be the safest plastic as far as chemicals leaching into my drinking water. I had no problems with the hanging system nor any of the other parts.
Have been using this reservoir for 25 days. I like to freeze some water in it before I carry. If the tube is frozen, it will not clip, otherwise it has been great. Unfortunately, this morning I found a leak near the bottom on the side. Returned it, am thinking that a fold with freezing water may have caused the leak. Since the original pack recommended freezing water with lemon juice to reduce plastic taste, it seemed the material could withstand freezing. Anyway, trying a second reservoir, I have really enjoyed the convenience of the fill and connect system.
I have had the same issue others had with the original hanger breaking off. The new design has been very reliable and does not break, as far as i can tell. I really like the quick disconnect which means you don't have to reroute the tubing every time you refill. And I find that the fold over top seals well and makes it much easier to fill compared to the screw on top.
I have a few sizes of these, this being the largest. Im not sure how people manage to break them, or have issues getting them open, they are dead simple. easy to clean, easy to fill. More importantly, if you have an issue, they will give you a new one. great company, great product
