Rated 3 out of 5 by from Great but careful with the lid The product is great. Very durable bag that can be stuffed into your pack without too much worry over breaking. But on my last 3 day trek in the dry Guadalupe Mountains in west Texas I found the cap was slowly leaking water through the threads of the flip top cap. lining the threads with tenacious tape did not stop the leak. There is no damage to the cap that I can see, so the sudden leaking is a mystery. Had to keep the bag upright in my pack to avert disaster. Not an ideal situation. I would recommend keeping a spare cap in your pack just in case.

Rated 5 out of 5 by from Amazing Water Bladder I own the 10L and fell in love with it the first time I used it. I have put this dromedary bag through the ringer, countless patrols getting jostled around in my rucksack along with deployment when I was in the military. The strength of these bags are unbelievable, I once had a friend fill up his water bottle from it when he had it on the roof of my jeep and after 10 minutes of talking he forgot it was on the roof I drove off and it fell while I was going around 30mph and it didn't break. Great for hanging as a shower and using to fill up my whole team's water when they need it. I can't say enough about this bag and I recommend it to everyone I come in contact with in the outdoor industry.

Rated 5 out of 5 by from Durable portable water carrier I've used a pair of the largest dromedary for 15 years now. Never had a leak. I've only ever used it for clean water. The bag does impart a rubber/plastic taste. Great when you are planning to spend a few nights away from water. I use these because they have been reliable. I've had cheaper containers break which can be very frustrating. My water filter screws onto the cap so easy to fill with filtration. The cap is a 3 way thing, you have a squirt nozzle, a small 1cm screw top, and a big opening. Well designed. Usually use the middle sized opening to fill water bottles.

Rated 5 out of 5 by from Heavy duty waterbag I have used the 4L bag now for approx 4 years without any issue, the 3-in-1 cap gets worn over time but is still functioning witout any problem or leak. The rest of the bag is as good as new. Two minor thinks that might have to be considered: 1. Then trying to dry the bag something needs to put in to allow it to dry completely. 2. The bag is black. Together with sunsine the water in it will get quite warm. This can be good or bad depending on the situation. In genereal I actually like this so I can double-use it as a solar-shower bag :) Most of the time when using that bag I do cycle tours and attach it on top of my rear bicycle rack. Definitive a "would-by-again"

Rated 4 out of 5 by from Great for the desert I own the 6 liter and several of the 2 liters. This is the most bomber backpacking water storage there is. They screw on perfectly to a miniworks filter, which is very convenient when you have to cover substantial distance between water filling areas. I wouldn't recommend treating water with iodine in them, as the taste lingers for a long time. Like a camelbak, it is worth taking the time to properly dry them out before long term storage. The three stage cap is convenient, and I've even used the 6 liter one as a passable pillow at night in a pinch.

Rated 5 out of 5 by from The best collapsible water carrier I've found. An excellent product, that performs as promised. I've used my 2L bag routinely for around a year, and it has come to replace my rigid Nalgene bottles and collapsible platypus bladder. The ability to connect with the micro works filter is a handy feature, but it's main strength is the ability to kick it about, stand on it, drop it, and use it as a pillow without it being anywhere close to leaking. The only fault I've been able to find, is that the water developed a plastic taste after a few hours in the bag. I had read other reviews and knew about this before I bought one, and the problems went after a few weeks. So I don't feel I can deduct points for this. Overall a brilliant product, although you tend to get weird looks if you drink straight from the bag in public.

Rated 1 out of 5 by from Bad rubber taste bought a 4l bag years ago from MEC and based on the great experience with that one just recently another one. This newer one produces a really bad rubbery taste to the water. I tried a lot of things as per some internet postings incl baking soda, vinegar, repeated wash/rinse, but to no avail. Not happy with this one. I wonder what MSR is suggesting?

Rated 5 out of 5 by from tough water carrier I've had my Dromedary for over 8 years. It has been through countless hikes, camps, hunts, fishing trips and storage. It has never failed, leaked or burst, going though hundreds of liters of water over the years. Highly recommended.

These new they impart the same plastic taste to water or have they fixed this in the new design?

Asked by: flournnoi
This has been laminated with an improved BPA-free food-grade lining which has also improved the taste of the water.

Do the Dromedary bags feature a (Nalgene wide-mouth size) lid opening compatible with the output nozzle of an MSR pump water filter?

Asked by: Theamazingrando
The opening is compatible with MSR water filters. The cap on this is a standard wide mouth cap.

Is there a way to hang these new bags. The old ones had a hole at the top so you can let it hang from something. These seem harder to have hanging from a tree or table to use easily.

Asked by: Frank
​The webbing around the perimeter of the bag is a great way to hang it.

The 2017 Dromedary bags have a different cap. We recommend contacting MSR for advice on using a hydration kit with the new bags.
