    Keep the fluids flowin' with the re-designed MSR Dromlite Bags.

    The MSR Dromlite Bags are a lighter, but equally tough, version of MSR's Dromedary Bags for the weight-conscious backpacker or camper. MSR Dromlite Bags take the hassle out of filling, carrying, and pouring water in the field. MSR designed their Dromlite Bags to withstand the most trying conditions. With a temperature threshold from freezing to boiling, and abrasion-resistant cordura construction, these sturdy Bags hold up to the most rigorous adventures. MSR added a low-profile handle making it easy to fill. MSR Dromlite Bags have added perimeter webbing allowing you to attach it to your pack or hang it up at the base camp. The bonus 3-in-1 cap ensures effortless filling, drinking, and pouring from the Dromlite Bags.

    Great gear

      This water bladder is bullet proof. If you are tired of going for water for cooking and camp dish clean-up then get this bladder. A six liter bladder will take care of the needs of a party of four from breakfast to dinner. It also makes a great water reservoir for a shower. Just attach a tube with a plastic shower nozzle, add some hot water to the otherwise cold water in the bladder, and enjoy a complete warm water shower.

      They do their job

      • Familiarity: I've used it several times

      I used a pair of these (6L version) on a few occasions, including a 10 day kayaking trip, and they do exactly what they're supposed to: hold water and don't leak. The large opening is compatible with my MSR filter connector (although I haven't had occasion to use it yet), the smaller screw off cap is perfect for drinking directly from it, and the flip top is perfect for emptying air from the bladder. I wasn't sure about the material at first, but after tossing it around on Maine shorelines for a summer, I'm pretty sure these things are more than durable enough for anyone who reasonably cares for their gear. The material also doesn't seem to impart any taste on the water, even after spending days in the bladder. Definitely my go-to recommendation for water storage in a kayak.

      Excellent Water Storage At the Campsite

      • Familiarity: I've used it several times

      I have a 4L Dromlite and if I'm honest I was a little on the fence about it when I bought one. I originally was thinking about using it as a solar shower on my sailboat (which it rocks at) but I decided to bring it along one time on a hiking trip and now I'll never overnight hike without it.

      Using it while hiking as a replacement for a water bottle is foolish, in my opinion. Where this thing shines is when you get to your campsite and get yourself set up. Many times you're not camping right next to a water source so this is a great option to walk to a clean water source, fill it up, and then hang it up. Once it's up there you have the next best thing to running water right outside your tent.

      If there's one downside to this bladder it's that I find it hard to actually fill it to capacity since it's an awkward shape. I think I can get 3-3.5 liters in it easily, which is more than enough for me at a campsite.

      Pro-tip; the 3-in-1 cap will fit on a Nalgene bottle (just in case you want something other than a wide-mouth lid).

      My New Favorite

      • Familiarity: I've put it through the wringer

      I use to use Platypus products almost exclusively but one of my ski/climb partners uses the Dromlite bag and I figured it was time to switch things up. I'm super happy I did. I used this on a recent road trip to Shasta, Rainier and climbing at Smith Rock in Oregon.

      3-in-1 Cap:
      This is where the magic happens. This is the reason I've gone with the bag over other hydration products. The versatility of it is unmatched by any other product.

      Option 1 (Wide Mouth):
      I can attach my MSR Guardian Purifier to it and fill it directly which it awesome since not many other containers can attached to the Guardian.

      Option 2 (Small Screw Cap):
      If I'm mega thirty I twist off the smaller cap and chug water. Great for when I need water fast.

      Option 3 (Flip Opening):
      This is one of my more favorite options. It is great for purging the last bit of air from the bag if you're trying to collapse it as small as possible to save on pack space. But the major reason I like this option is because I tend to crush water when touring, hiking, climbing, etc and by drinking from this smaller opening I get less water and it forces me to pay more attention to the rate that I'm drinking.

      I had this in my pack near my sharps (crampons, ice screens, cams, etc) and never had issues.

      Hyrdate to Dominate

      • Familiarity: I've used it several times

      Whether youʼre settled down at base camp with the crew or hiking your way up a mountain, the dromliteʼs capacity and durability cannot be competed with. Despite that
      the material is a bit lighter and thinner than the dromedary, I am not afraid to put this bladder through the wringer, as it makes itʼs way in and out of my pack, hangs on trees,
      and passes through the hands of many crew members. MSR also accounts for variety with the types of spigots and hydration kits they offer. Itʼs a valuable piece of hydration
      gear whether riding solo or providing for the whole gang.

      A necessity

      • Familiarity: I've used it several times

      This light weight water storage option is a must. Its great to have extra capacity for more water on hand, the bag fits almost completely out of sight. Lots of different pour options to control the amount of water coming out is a great feature. H20 is life!

      Mount Whitney Hike September 2015

      • Familiarity: I've used it once or twice and have initial impressions

      I bought the MSR Dromlite Bags for my Mount Whitney Hike. Even though I didn't backpack the bags with water in them on the hike, I did find it as nice extra water bag to fill up with water from the water sources near our camp sites. I used the extra water for cooking, cleaning up pots and cups, and refilling my hydration bag and water bottles for the continuing hikes.

      Very handy and didn't take up a lot of room in my backpack when carried empty.

      The Platypus is Dead

      • Familiarity: I've put it through the wringer

      Used to have a Platypus. Needed to find a way to carry water without the big Nalgene. Platypus is super light, folds. Found that over time it breaks down, first few uses it was alright, then I started to worry. If I lose my water the day is over... Picked up one of these in a 2 L, so much more durable. Definitely my new go to. Plus the cap has a squirt feature which makes sure I dont go ahead and gulp the water too fast, ensuring pacing of the drinking. Awesome addition to my pack.

      Look at all that water!

      Not in the lake, in the bag. The MSR Dromlite kicks ass. I don't mind pumping water, it's peaceful and my right bicep looks great.

      What gets my goat (HA!) however, is mowing down on some delicious camp chow, then reaching out for a drink only to come up EMPTY.

      I'm less zen about pumping water with a gob of rehydrated lasagne lodged in my esophagus.

      Enter the Dromlite - 6 liters of water. Add the MSR Spigot cap and this beauty will keep everyone in camp hydrated and happy.

      Look at all that water!

      Kicking back at camp Crystal Lake

      That Jason Voorhees feller seems like he'd machete you on a late-night trip to the lake for a drink.

      We foiled his plans with the MSR Dromlite, 6 liters of glorious, murder-free water.

      I bet he's crying under his little hockey mask.

      Kicking back at camp Crystal Lake

      Dude, they make AWESOME iron-on transfer paper now. I found some at Walmart that was $10 for 3 sheets - robbery. It's cool though, almost like vinyl.
      I always want to represent but I find that most of my gear is soft and not suitable for stickers. Every company should make a Backcountry version of their products!

      Weights are Wrong

      • Familiarity: I've used it several times

      The weights listed on this page are wrong. The weights listed on both the packaging and the MSR website ( are (2L) 4.6oz, (4L) 5.1oz, (6L) 5.7 oz.

      Still a great product, but not as light as advertised. I only noticed it while shopping around for a lighter alternative to a different hydration bladder.


        Holds a generous amount of water, but packs down to and weighs almost nothing. The interface with MSR water filters makes refilling in the field simple. The 3-in-1 cap has a variety of uses, and is well thought out.

        The best bladder!

        • Familiarity: I've put it through the wringer

        I've had a 4L Dromlite for about 8 years and it's still going strong with nary a leak. I used to use Platypus bags but got tired of them eventually getting brittle and leaking at the corners. Not a problem with the Dromlite! For easier pouring, I highly recommend the Spigot Cap (CAS0051). I've attached some cordage to the grommet on my bag so I can just clove hitch it to a branch once I get to camp.

        Hydration sack!

        • Familiarity: I've put it through the wringer

        I used the 6 liter Dromalite all summer last year as a wildland firefighter, and it stood up to the abuse! I was a bit concerned at first and thought I should get a dromedary but this thing killed it. with the hydration kit this thing was great. I still use it when I want to take extra water or I'll only put 2 or 3 liters in it at first and when I get to camp pump some water and fill it all the way up. I have loved having this. and it stood up to some real abuse

        Great water bag

        • Familiarity: I've put it through the wringer

        I have the 6L bag and it is really big! I don't even use the whole thing. I just fill it up for a days worth and get all the air out of it. During the summer months it keeps water around or below room temperature without Ice and when its 90 degrees outside. I would personally suggest getting the 4L because it will fit in you pack better but it is all depends on what you are doing. If your going on long backpacking trips in the summer then go for the 6L or bigger, but if your only doing day trips and have no intention of long backpacking trips then I would suggest the 4L.

        Everything on the water bag works outstandingly. I haven't had a problem with the cap it is actually very helpful. The little part on the cap posses no problem to leaking. The thin fabric is really lightweight and tough! I have put it down on sharp rocks and it shows no sign of ripping or weakness in the fabric. MSR really hit the nail on the head with this product, it is a must have! This is much more efficient than 6 water bottles. Now you bring this in the sleeve in you pack and a water bottle or two and your set for water!

        Could I hook up a hose and sawyer filter to the dromedary? Im looking to use this Dromlite as my dirty water container and gravity filter straight out of it.

        does the 4L fit in the hydration sleeve/back panel of osprey packs?

        Great bags, I've had/used a couple for about 4 years now, great for stashing behind the kayak seat, very duable. Recently lent them to a friend that stored them wet now have a terrible smell/taste any recommendations for cleaning?

        Best Answer

        2 tablespoons of bleach per liter of water, let it sit for about a half an hour, rinse it out, leave the cap off and poof it up a bit to open all the nooks and crannies, let it completely air dry for a couple days...don't let your friend borrow it again

        I normally use little splash of bleach and hot water and let them sit. If that hasn't worked, and it sounds like it hasn't, I'd try a couple tablespoons of ammonia and hot water... but you will have to be very, very careful to rinse them out *thoroughly*. Ingesting any portion of ammonia is a bad idea. However, ammonia can clean most anything.

        what are the measurements for the 2L bag?...

        what are the measurements for the 2L bag? I have a pack dog who can carry 20+ lbs and wanted to see if this might fit in his pack...

        I've got a few questions about this bag:1....

        I've got a few questions about this bag:1. The description says "food-quality polyurethane" so I'm guessing this is BPA free. Is that true?2. How's the taste out of this bag?3. I have an MSR SweetWater Microfilter, and it comes with a "watter bottle adapter" to let me fill directly into a bottle. Will that fit one stage of the 3-in-1 cap? [The adapter has the same thread as my 750mL Camelbak Better Bottle if that helps.]
