Besides you and your bike, water is perhaps the single most important thing for long rides, and the MSR DromLite water bags are a great way to carry it on your bikepacking adventures. The DromLites are available in three sizes and pack a lot of thoughtful features making them far from ordinary. MSR DromLite The MSR DromLites are available in 2, 4, and 6 liter options. I carried two of each size along on my White Rim bikepacking trip. Each bag comes in well under one-half a pound with the largest weighing just 5.7 ounces and the 2 liter 4.6. The DromLites feature a three-in-one cap. Unscrew the large cap, and you can easily fill or clean the bag. The small screw-cap is the perfect size for filling other bladders, bottles, or large containers. The small flip lid is great for drinking from, for filling smaller vessels, or for more precise pours. It also makes a high-pressure stream when squeezing the bag that is ideal for rinsing cookware and utensils or sticky sports drinks from bottles. The caps also allow connection with MSR accessories such as the hydration kit. MSR DromLite The interior of the DromLite bags has a BPA-free, food grade coating that not only makes cleaning easy, but assures you get no off-flavors in your water. A side-by-side comparison with another bladder revealed just how plasticy the water from the other bladder tasted. The exterior is 200-denier Cordura for toughness without a lot of bulk. For bikepacking, I believe this to be the perfect choice. Though not as tough as the Dromedary bags, the DromLites are plenty stout, especially considering they will normally be packed in your frame bag, backpack, or panniers. The DromLites are 30-50% lighter than the same volume Dromedary bags, and the DromLites I used on the bikepacking trip saved 13 plus ounces over what the same sized Dromedary bags would have weighed. MSR DromLiteThe DromLites feature a riveted hole in the top of the bag for hanging. However, another nice bikepacking use of this is for anchoring your tent in rocky or sandy environments. A full 6 liter bag weighs nearly 13 pounds and makes a fairly stout anchor on its own. You can bury the bag in sand for extra holding force or you can empty the bag and place rocks on top of the bag for another anchoring option. MSR DromLiteThe MSR DromLites are a great choice for water transport on long bikepacking or touring adventures. They are tough yet light and packed with features not found on other bladders and bags. Plus they are made in the USA. The 2 liter bag retails for $26.95, the 4 is $29.95, and the 6 liter sells for $32.95. They can be purchased at MSR retailers or directly from MSR’s website.

    Thanks for the review, looks like a good product. Please don’t take this as snarky, but if one would pile rocks on the bag to use as a tent guy anchor, wouldn’t it be a lot easier on the DromLite to just tie your guy to the rock?
    Similarly, burying a water bag to create an anchor in sand or snow must surely be a last resort in the total absence of any buryable, found object.
    Did you try a DromLite in an Anything Cage?

  2. How do you store this on your bike?

  3. As to transport – I’ve stashed one of these in a front pannier with good effect, but does wobble a bit. As I transition to a newfangled bp setup, I see this in frame bag. Save yourself time in visualising the weight: they weigh a shade under sweet FA.

  4. I have a 3 liter and a 5-liter MSR drome bags that I started to carry with me when I did the Great Divide mountain bike route. They are wonderful. I keep the 3 liter bag full and put in my front pannier with a tube running across my handlebar so I can drink while I’m riding the 5-liter bag I carry empty until I know I’m going to someplace where there’s a scarcity of water. I just recently used both when I cycled the white rim road in Canyonlands In Moab Utah. On Facebook, I am “the little bike that could.”
