It's durable, doesn't taste like plastic, is easy to fill and clean...I love this thing! The polyurethane lining is bittersweet. It keeps the tube from cracking in the winter but mine got twisted where the tube stems from the bladder. After I pulled it apart to untwist it, I couldn't get the darn thing back together! As long as you keep it from twisting, this puppy is a work of art!

I used this bladder for five months of intensive hiking and loved it. Then the same thing (exactly) that happened to the reviewer "Twisted" happened to me. "After I pulled it apart to untwist it, I couldn't get the darn thing back together! " It is now useless. This is a major design flaw. Beware.

I have been using platypus and camelback bladders for as long as I can remember, and this is far better! The material is bomber, and tastes far less like plastic than the others. It also has an easy opening, which I can operate with gloves on and doesnt need to be really cranked closed to seal properly (a real problem with camelback bladders). My only gripe is the 90 degree bend at the bite valve - which makes this really hard to run through the insulated sleeve on my backpack (this is my fault for not reading the description!). Overall a really good bladder, go for this above all others

This is the only dromedary you will ever need. I use it with my MSR filter pump and it works with no issues. The mouthpiece doesn't leak wether or not you close it. I just leave it open and save time stopping to open it. It fits between my pack and the mesh frame liner on my backpack if I'm carrying a bear keg, otherwise it fits easily in the inner dromedary pocket of my pack. My pack only has a single clip for the bag, so I rigged a small piece of nylon rope between the loops to keep it from sagging, but it doesn't really sag that much since the outside of the dromedary creates some friction with my pack. Doesn't sag at all when its full. Been using mine for a couple of years now on many peak bagging expeditions (12 2-4 day trips) and no sign of wear yet or functionality problems. No funny smells or tastes either. As far as I can see, this will be the only one I will ever need to buy.

For all backpacks with an internal hydration pocket, the extra durability of the MSR Hydromedary is key. MSR's standard size cap is easy to open and assures a tight seal. Highly recommended.

I have it for three years and it is the only hydration bag that have a big flow of water!
I fracture my tooths. and it's the only valve that can stend it :)
the bag is very durable
the only flaw is when I use it in my 70L big bag and staf start pressure on it it can leak from time to time even from a clouse valve. and I need to make sure that the bag face down.
I will still buy it again!!!

I'm stoked for this bladder, I've had others and so far this has the least amount of plastic taste, it seems durable and the bite valve works well. I highly recommend it.

I use this around camp, in a day pack, or in my full pack. It is fairly durable and has a long tube so you can turn any backpack into a hydration pack.

I love it. I had one and i flipped my mt bike and landed on my back and that one kinda leaks around the cap now so I got a replacement. Love it I can just hook it up to my filter and fill up my water it's awesome.

I have used Camelbacks for years and they have done the job, but this hydration bladder by MSR tops the list. Never worried about it tearing or popping, the water comes out very easily and am yet to experience any leaks.

Been using this in a Columbia internal frame pack, works great! No leaks, easy to fill.
