CamelBak90352 Omega Water Reservoir, 100 oz., Black

Filled to the brim this bag holds 3.2 liters. It seems very durable. It is easy to fill and the cap closes securely. The mouth is wide so you can easily add ice. The hose is neither too long nor too short. The bag imparted no taste to the water on the first use. I had no problem placing an Osprey magnetic clip on the hose. The hydrolink attachment for the mouthpiece is easy to work and very convenient; among its other virtues it allows you to easily turn the bite valve to the best orientation for drinking. The hose is completely detachable from the bag, which makes drying out both the hose and the bag more efficient. I thought I might have preferred an angled mouthpiece, but now having used this bag I don't miss it at all.

This is now my new long-trail backpacking bladder for when I need a little more water than my 2 liter, or when it's hot outside and you need more ice. I use this in multiple sized packs, primarily 5.11 Rush bags, and it works great. This bladder is very durable and a bit thicker material than most other bladders. The quick disconnects are great for cleaning and packing it away, too. This is a taller bladder than most, so check your pack's dimensions before ordering. It's a little tight in some of my shorter bags that have a bladder compartment, but it still squeezes in without much extra effort. The longer size means you don't really have to secure the top hook to a support to keep it upright, though. Just slide it in your pack's bladder compartment and it stands up on its own. Should fit fine in any standard Camelbak-type pack.I first used this bladder on a 9.5 mile high altitude hike. My friends both had 2 liter bladders and ran out of water close to the end of the hike. I still had just over a full liter left and could have comfortably gone another couple hours without hesitation.Only con I have with this bladder is that you cannot leave it full and then disconnect the hose at the bottom without water coming out. There is no mechanism that closes off at the connection to prevent water from spewing out. Make sure to disconnect the hose only if the bladder is empty or if you're holding it upside down.

This is quite an upgrade from the current consumer-grade Camelbak bladder, but there are a couple of things to be aware of. First, the twist caps on most of the new consumer Camelbak bladders have a nice quarter turn to open or close. The cap on this one is like to older versions which might require more than a full turn. That quarter turn setup is nice and it's too bad it's not part of this.The other thing to be aware of are two issues with the bite valve. I believe the real military version comes with a bite valve cover. This doesn't, so you have to buy one separately (if you want one....how dirty are you gonna be??). The second thing is that the bite valve isn't set up at a right angle like the consumer version. It might seem like a minor annoyance (all right, it is!) but with the consumer bladder the valve can be left hanging, pointed at one's mouth. With this one you have to take the hose and bend it into a 180 to get it into your mouth.OK, enough with the negatives. They are more than compensated (for me anyway) by the heavy duty construction and the quick release connectors. This has been nicely engineered. A subtle feature is the way the shutoff valve is designed. When the valve lever is pushed away from the user, the flow is shut off. You have to pull it toward you to to start the flow. Why is this cool? Because if your hose valve snags on something this arrangement will tend to cause the valve to close, thus saving the owner a good wetting. There have been a few times in the past this feature would have come in handy....

Already have one for my backpack, needed a second one for enough water for my dog as well on long hikes. Love how easy it is to clean and the covered drinking hose.

I bought this bladder for my Maxpedition Condor II. It is the first hydration bladder I've owned so I have nothing to compare it to, but I am very impressed with the build quality of the product.The wide mouth that appears to be common on all hydration packs makes filling it up very easy even as it becomes heavy under the weight of the water. There is a nice handle integrated into the mouth that looks to be designed as to allow for not only at the sink fill ups, but also the ability to dip it into a stream and hang onto it as it fills on its own (of course you'd want to treat water gathered from a body of water).The cap that seals the mouth seems to do a fine job of keeping everything in. However, much like the very thin caps found on water bottles, there is only about 1 turn on the threads. This makes starting the lids threads into the mouth can be a little tricky if you haven't taken note of where they begin on each part. This could (but has not, so far) result in cross threading of the lid and an unreliable seal. This isn't worth knocking a star off as it makes for a quick seal as long as you're careful about what you're doing.The bladder itself is made of a much thicker material than I would have expected. I've watched videos of men who would swing this bladder by the hose and smack it into the ground to demonstrate its durability. I'm not talking about a love tap, either. While I haven't, and probably won't ever attempt that with my own gear, I'm confident that the bladder's construction will never be an issue when it comes to overall durability.The hose connects easily at a nipple found at the bottom of the bladder. The fittings on the hose and bladder are similar to those found on an air compressor's quick-connect. There is a button that rounds out the locking connection to allow the nipple to slide out of place. This is difficult to explain as I've never seen a fitting quite like it anywhere else, but it does make for a secure fit that I don't think will ever slip unless there is human error involved when attaching it.The hose is insulated and the insulation stays right in place on the hose thanks to a rubberized backing on it. On the user-end of the hose, there is an on/off thumb switch that seals the hose so you don't drip anything out while not in use. It comes with a rubber bite piece that is fairly thick and looks as though it will last quite some time. Also included in the package was a plug that allows you to either seal the bag while the hose is not attached, or snap your mouth piece into it for safekeeping. I used a piece of 550 cord to make a sort of quick-detach loop. I put it around the cap so that when I'm hiking and don't want to worry about dirtying up the mouth piece, I can hang it from high up on my shoulder strap from the cap, or detach it and use it to seal the bag when needed.Lastly, if you've previously set up all of your compression straps, and shoulder straps, and hip straps, and everything else WITHOUT this bladder in place, your pack is probably going to fit a little funny if you put this in full. I'd recommend putting the full bladder in place with all of your straps loosened, packing your bag as normal, and then setting your shoulder straps and all that other good stuff. Otherwise, it's a big uncomfortable bulge in your back until you suck almost all of the water out of it.
