Heaps better than others I’ve owned

Having the wide mouth to fill the bladder is so nice, and it makes dumping ice in soooo much easier. The quick detach hose makes placing the bladder in my back a ton easier than conventional tubes. The bite valve was a bit odd compared to what I’m used to but not a deal breaker. It just felt different. My only criticism is when putting the bladder away after use, draining the hose below the quick detach isn’t as smooth as it could be and if done wrong I could see it growing mildew easily. So just be sure to pay attention to the water in the hose and you’ll be ok. The best part is, it doesn’t taste like squirt gun water like some brands do!

Quick Release Not Well Engineered
Rudy 713
9 years ago
I had last year's 3L model which I modified with a Sawyer quick release. I placed the junction approximately six inches from the bite nozzle. This worked extremely well and allowed me to easily refill the reservoir without having to open the backpack. However, the 3L was a bit big and bulky. When Osprey came out with new reservoirs this year, I picked up the 2L and sold my modded 3L. I thought, great, Osprey added a quick release, well done. On paper, it's great. In practice is another story. Osprey placed the quick release in an extremely vulnerable position. In my past five backpacking trips, I've had to remove my pack every time to reconnect the drink tube to the feeder tube. Every time, something in my pack would push against the quick release mechanism and disengage it. Nothing sucks more (pun intended) than being tired and thirsty and having to drop your pack because your reservoir isn't feeding water. On top of that, the quick release mechanism is difficult to tap into with my Sawyer refill tube and I always end up spilling water into the pack. The reservoir itself is great and I like the incorporated handle and back panel. It's much less bulky than the previous generation. The quick release mechanism, though, was badly engineered. As soon as I pick up some tubing, I'll mod it like I did for the previous gen. That'll solve my issue with it always disengaging and it'll make it much easier to refill.

Beware the quick disconnect site

9 years ago

After reading the product reviews, I was very careful when packing my backpack to protect the red quick disconnect button from inadvertent pressure. This prevented all but one instance of disconnecting during a day of travel on a 7 day backpack. As stated by others, the location of this feature should be changed to make it easier to access from outside the pack when you might want to fill the reservoir without taking the bladder out of your pack. The stated method of disinfection requiring an additional kit is also not user friendly IMO. All my other bladders have been much easier to clean without special tablets and tube cleaning devices.

Osprey nailed this one

8 years ago

I thought hydration packs could not get any better before I bought this one. The features on this are amazing. The disconnect is half way up so you don't put your hydration pack into your pack only to remember you didn't connect the tube and have to pull it out. It also has a solid back so you can easily (forcefully?) cram it down behind your sleeping bag and other pack items. The big opening at the top is great for cleaning. The blue handle allows you to carry it to the stream to make more water. The magnetic clasp makes securing and grabbing the tube easy. And the water flows well through the 360 degree tip. I wonder how they can one up this one?

Easy and high quality

5 years ago

I went into REI never having had a hydration pack before. One of their staff members explained to me the differences between all the options and I understood why this one was worth the money. Love the hard back feature of this, so all of the water does not pool at the bottom. Super easy to detach the hose, fill, and clean. Thumbs up.

Great design for the nozzle.

9 years ago

There are two aspects of this Camelback that I want to shower praise on. 1. The nozzle is housed in this continuous piece of plastic that has no nooks and crannies that accumulate dirt and debris. This is a big deal, as anyone who has used a Camelbak for any extended period of time can attest. The drink nozzles on those things get pretty gross--not the kind of thing you want to put in your mouth. 2. The magnet that snaps the nozzle to your chest strap is such a brilliant little piece of engineering. I used to spend so much time fiddling with the hook on my old Camelbak. Usually I would just end up letting it kind of dangle there.

New to me design - super functional!

5 years ago

When it came time to replace my ~8 year old Camelback bladder, I was very wary of all the new bladders that look like they're doing too much. Someone in store highly recommended this and I'm glad they did. Being able to detach the hose half way makes it so much easier to clip onto my pack especially when refilling on the trail, the sliding seal is way easier than the old screw tops and the hard back makes it so my pack doesn't bulge when the bladder is full. The mouth has a locking mechanism that it took me way too long to figure out was there. All around great water bladder!!

truly great

7 years ago

So this is my first water bladder experience and so I can't speak to its performance in comparison to other bladders out there but I will say that filling it up is a breeze, the quick release of the tube is ideal especially for me when im switching from bag to bag for my adventures. One thing that I wish it did have that i noticed on some other bladders after purchase is that I wish the top where you actually attach & hang into your pack was designed to be a hook. I had to come up with a paperclip sort of fix to connect my bladder to the interior loop inside my smaller daypack. This is very minor but just a little detail that would make it more universal and versatile.

Tastes like plastic

5 years ago

This reservoir seems very well constructed and is convenient to use. One needs to be careful of the quick release being sure it is completely engaged. The only problem I have is that the reservoir imparts a "plastic-like" taste to the water. I thought this would diminish with use but it has not. For me this is a non-starter. I no longer use this item. I am surprised that more reviewers do not mention this. Perhaps Osprey has changed the formulation. But once bitten, twice shy.

Good design but…

3 years ago

Good design but supposedly you can drop it into a full pack. You can not. I tried and finally dumped out my half full pack to place the bladder. I had a 30L Pack only half full. I do like how easy it is to clean but two issues: the magnet is a joke and there is no mouth piece cover. Take your pack off, set it down only to realize the weak magnet has released your unprotected tube and now your mouth piece is writhing in the dirt. I spent my entire pack trying to corral my tube, but it’s a solid system so I’ll figure something out.
