The MSR DromLite has a new 3-in-1 cap that is not compatible with the accessory kits (like solar shower and hydration kit) as was its popular predecessor. That said, if you want to buy the new DromLite, but you want to use your old accessories still, just give MSR a call. They will send you a cap that will work (the old design) free of charge.
Performance Comparison
This Top Pick boasts an insanely packable design that isn't only durable but incredibly lightweight as well. It's a perfect option as an additional reservoir for day hikes, backpacking missions, or hanging out around camp.
The DromLite Hydration bladder can be hung from rocks, stuffed into backpacks, and dragged pretty much everywhere. Its lightweight and packable design in addition to its vast adaptability makes it a Top Pick.
Ease of Use
The DromLite is an easy to use hydration reservoir that can be turned into a bladder. The key feature is its well-engineered 3-in-1 cap that can be used in three different ways. First, the Nalgene-sized open houses a durable and sturdy tab that makes holding the bladder easy while filling. This opening is compatible with the MSR pump and a plethora of other accessories. Second, there is a second screw top opening that attaches to the first screw-top lid which provides a medium flow of water, perfect for filling up a water bottle or hydration bladder. The third is the trickle spout. This is an even smaller spout, perfect for taking a quick drink.
The hydration kit that can be ordered separately from the DromLite is rudimentary at best, attaching to the secondary opening. The bite valve is comfortable and offers a shut-off valve open that doesn't get sticky or gummed up after multiple uses. Also, the bite valve can be switched out for other options that are compatible with HydraPak or Camelbak if you prefer another mouthpiece. Our major caveat is that the hose is (obviously) not quick-release and is not compatible with other hoses.
This bladder is not designed to fit inside of smaller running packs or thinner profile hydration packs. That said, it did well, fitting into larger hydration packs with a wider profile. Some backpack sleeves tested could not house it. Overall, we'd recommend assessing how you want to carry this reservoir before buying it to ensure it fits in your back.

Users of the DromLite prefer to use the additional hydration kit (mouthpiece and hose) for adventures where you don't want to dig through your pack to get to your water. Otherwise, the DromLite is best used as an additional reservoir or a general water-carry system.
Ease of Filling
Equipped with a durable and burly handle that allows you to fill your DromLite bag from a tap or river easily, filling is simple. That said, while the handle is sturdy and doesn't deform under the weight of the bag while it fills, we felt that other hydration bladders are easier to fill from trickling streams or super shallow mediums.
While you can place this bladder down on the rock or trickle, this design cannot capture as much water as the Hydrapak Shape-Shift Reservoir that features a fold-top design and can easily collect water from trickling streams. You simply place the fold top collector on the rock, allowing water to trickle inside. The screw-top design doesn't allow this use. That said, it's perfect for plunging into a lake or raging river, collecting water quickly.

One thing that we love about the new design is the plastic material that doesn't get soaked when collecting water like it used to. The new material (that isn't absorbent nylon) easily wicks away water and grime, making it more convenient to put back into your backpack.
Ease of Care
This bladder is more difficult to care for than other models tested in this review. The Nalgene-sized opening is small, and you can't fit a hand inside to clean the opening. Luckily, the 3-in-1 cap comes apart quickly and is super easy to soak and scrub. The exterior plastic material is translucent so you can monitor any potential bacterial growth, which is an improvement from the previous design.
To clean this bladder, use a cleaning tablet or be diligent about making sure you rinse and dry your bladder after use. In our testing period, we simply rinsed and dried and didn't notice any build-up over time. If you plan on using a sugary drink (which you can with this new design), be sure to use both a small brush and cleaning tablets. Then, throw it into the freezer (without water inside) after its dried to ensure no bacterial growth.

If bacterial growth does ensue (for example; you forgot to clean your bladder and left it in your backpack for a week or longer!), be sure to scrub it well with a small brush and, again, use a cleaning tablet. The construct of this bladder will make it difficult to reach every nook and cranny.
Consider a tablet like
Hydrapak Bottle Bright; this formula is biodegradable, non-toxic, and non-chlorinated to help ensure all potential bacterial is removed from the bladder.
Weight and Packability
This is one of the lightest and most compressible hydration bladders you'll find on the market. The outer materials are durable yet flexible, folding efficiently and effectively. The new design is not nearly as bulky as the last model, making it a packable option for any sport that requires lightweight travel. This is a big reason that it's our best recommendation for backpacking.
This bladder, when empty, packs really small. A perfect option if you need to store your bladder on the go and space is limited.
Quality and Durability
Constructed of a new film with welded seams, MSR says that it offers "reliable durability," and we agree. Through our testing period, we threw it into backpacks, loaded it into coolers, put it in the freezer, and smashed it all around the crag. We hung it (and it fell numerous times) from rocks and sat on it too many times to count. We even had the dog drink out of it and play with it for a while. After all this abuse, the film, seams, and cap held up!
We pulled at the welded seams, trying to see if they would delaminate, and they don't budge an inch. When filling the bladder and squishing and squeezing it in all directions, the cap didn't leak at any of the screw points (despite some potential failure points). While this new construct makes us want to take care of the bladder a little more carefully than the previous version, there are no noted durability issues in our time with this bladder. In hand, it feels less durable because the materials are thinner than the previous design, but performance-wise, it's still a beast! The durable exterior is designed to withstand punctures, making it an excellent option for hanging from trees or rocks around camp.
Best Applications
The DromLite provides Herculean versatility. It can be hung pretty much anywhere, packed into tight backpacks, or put under pressure. It can function as a hot water bottle, hand wash station, sunshower, a water reservoir, and more! It can be strapped to the outside of your pack (if needed) or packed away to fill the smallest spaces in your backpack. Also, it can be frozen or even warmed up, maintaining its integrity through all of it. All of this in combination with its durability makes it our favorite for backpacking, although that's not all it's limited to. Nearly any outdoor adventurer can find a place in their kit for the Dromlite.

Value
This product is super high value! If it hadn't already won a Top Pick, it would be our Best Buy award winner. It comes in 2L, 4L, and 6L options with retail prices ranging from $27 to $33. A steal for the value of the product.
Conclusion
The MSR DromLite Bag features a new design that is still durable but more lightweight and packable than its well-known red predecessor. It comes in a variety of sizes and proved to be one of the most versatile hydration bladders tested. Because of its lightweight versatility that won't fail you on the trail, it's our go-to for backpacking and hiking.
This reservoir proved useful when taking the hour-long approach up to the lesser trafficked Cave Wall in Indian Creek. We were able to store extra water for ourselves and the dog in these hot arid conditions. This Top Pick for Backpacking is our favorite for overnights and day trips for its grand versatility.
