Generally Indestructible
I have been burned by bladders in the past, but these things are actually good enough to be your primary water reservoir. They stand up to treatment that goes beyond "harsh" and strays into "abusive" without issue (e.g. being stuffed, full, into the bottom of a voyageur pack and then slung onto rocks and into canoes with heavy stuff bouncing on top of them). I assume that running over one or shooting it would puncture it, but I don't plan to test either theory so YMMV. Only critique is that the intermediate pour spout lanyard is too short and makes closing the pour spout a pain.

Good bag
We had to rinse a bunch of times to reduce taste, added a touch of vinegar, and after a number of times it actually is pretty solid, we used it to carry water on a 3 day backpack trip. If I could have I would have gotten a carabiner on each grommet and probably put my own string through those and hooked it to my bag. When full the 6L size was a little snug but eventually fit into the top bag compartment of my backpack. I did have it leak once but I think that was because somehow the little valve got pulled up on something. I took note of this going forward and just made sure I knew how I was positioning the top of the bag. On the trip though no leaks and it was fine and worked well and can even handle boiling water in the winter and stuff. We carried water in this and in smart water bottles which are each a liter. We filled the smart bottles from this dromedary bag. They where just lighter being 1/6th the size to use and maneuver. Plus they acted like a decent measure of how much water was left in the bag as if we used 3 of those bottles we knew there was 3 liters left. Otherwise this was good and to clean we just washed with soap and stick a paper towel roll into it to keep it open and let it try, you can even clip the cap to the string around it to keep it all together while drying. Quite good.

Absolute Unit of a Dromedary
I had owned one of these previously during a seasonal NPS Summer/Fall work session doing trail construction in the American Southwest, and recently had an upcoming multi-day backcountry hike where I would need to supply water for myself and others, and this was exactly what I came back to because of the rugged durability I knew this dromedary could handle - I have used this as a pillow, solar shower, sat it on jagged volcanic rocks, scraped it on trees/branches, and have never had it leak once, at camp or in my pack. I have never had any sort of a plastic/rubber taste in either that I have owned, and the ability to convert it into a hydration bladder with a hose kit (albeit an obnoxiously large and heavy hydration bladder) was the cherry on top of it all. The stock lid that it comes with does have two spouts for various flows, but I personally use the MSR hydration conversion kit to attach a tube for pack carrying/drinking. Overall a great versatile piece of hydration equipment if you need a lot of water in remote environments, or if you need to carry hydration for others.

Top of the Line Water Bladder with Great Durability and Large Capacity
I have purchased and acquired a lot of gear through my time in the US Marine Corps, specifically for training operations and deployments. This is by far one of my top purchases / acquisitions I made. Among the things I have noted about the MSR Dromedary, these are the biggest strengths.Durability- By far the biggest selling point for me. The Camelbak bladders I used to use had no reinforcement, and would pop under a little bit of weight. That is a major issue when you consider the bladder is in a rucksack packed for an operation. The Dromedary, on the other hand, is reinforced and is near impossible to pop (from my experience).Capacity- The Dromedary has a variety of sizes, I have the 4L. That gave me 33 percent more water than my old water bladder while still fitting into my bladder pouch on my pack (although it is a tight fit when full).Water Flow & Leakage- I not noted any leakage aside from minor leaking at times if I do not tighten the screw cap on all the way. Water flow from the hose (from the conversion kit) is perfect. I haven't had issues with it getting kinked or knotted much, which would reduce or stop water flow.Straps- The Dromedary has heavy duty straps that outline its edges, which I have used to be able to secure it into packs and pouches in multiple fashions.Overall, this is one of my favorite purchases I have made as far as my gear goes. I highly recommend this product to anyone looking for a water bladder with a little extra durability.
