Our Verdict

The Camelbak M.U.L.E. has since its inception been one of the most popular hydration packs for tons of uses. But how does it stand up to the test of time? While Camelbak had the market cornered with their early innovation in the at one time small market of hydration packs, they're now under fire from manufactures all around the globe. Camelbak revamped the M.U.L.E. to meet some of these demands by updating details of the hydration bladder, various accessories, and the overall fit.

CamelBak M.U.L.E.
CamelBak M.U.L.E.
Camelbak did a great job in building the M.U.L.E. out with the right materials—the pack's shoulders, back panel, and sides are very comfortable. However, our main complain is the pack's lack of rigidity, which contributes to its tendency to turn into a tubular shape against your spine rather than keeps its natural shape. This creates pressure points in the front of the shoulders, and in the center of the back when the pack gets loaded up. While this isn't an issue when the pack isn't full, we found that in the beginning of rides when we were loaded with 3L of water, clothes, and food, that the pack was a bit more uncomfortable than others. We enjoyed the shoulder support, and how the shoulder straps met with the pack. We found that this design is crucial to the overall stability of the pack.


The M.U.L.E.'s strap system did a pretty good job providing the pack with stability while on the bike and while hiking. We really liked the contoured shoulder straps and its confluence with the pack, that widens into a patch that sits well between your shoulders. We found that overall, the pack was very stable. The well designed adjustable height sternum strap also provided additional stability.

However, we were thoroughly unimpressed with the simple webbing hip belt. We'll be the first to admit that we didn't use it on this pack, but maybe if it weren't so insignificant, it could've propelled the M.U.L.E. even higher in the rankings.

Ease of Drinking

The updated CamelBak M.U.L.E. now includes a clip for the hydration hose to keep it from flopping around.

As with all CamelBak packs, water delivery is very good with high flow from minimal effort. We were happy to see that CamelBak has updated the M.U.L.E. with a clip that helps keep the hydration hose at bay while riding rough trails. However, we got spoiled by the magnet on the Osprey that holds the mouthpiece right in front of you and gives hands free or almost hands free use, and preferred that design.

Ease of Filling

As with all the CamelBak bladders tested, the side opening of the bladder is easy for filling in a shallow sink, but proves difficult to clean and to fill in other situations.


This pack is very light considering how much gear it carries, and came in on our scale right around the Osprey Raptor 10.


As with most CamelBaks, we give this high marks for durability. No leakage was detected and we expect this to last longer than average before the bladder or plastic parts need to be replaced. However, the mouthpiece design of the CamelBak pack seems rudimentary to the other packs we tested, and tended to become a bit squished over time, leading to leaks.

Ease of Cleaning

While CamelBak's bladder design is good for shallow sinks, it's somewhat of a pain to clean in comparison to top zip bladders. Though CamelBak has a cleaning kit, it adds cost, complexity, and one more piece of gear to break/store. We much preferred the top zip due to ease of cleaning, which was a large priority to our testers.


The Camelback gets high marks for the amount of storage it has relative to its weight. There are three zippered pockets and an exterior sleeve where you can stuff in a jacket. All the packs that have more storage are generally much heavier. The M.U.L.E. hits the sweet spot of being light but having plenty of room for a day hike or ride essentials: food, rain jacket and a light warm layer. The only option that gives more storage for weight is the Osprey Talon 22 with Platypus Big Zip SL which has a lot more storage and is lighter.

Out of all of the helmet carry designs, we found this one to be the worst. Unless the pack is almost empty, the helmet can't fit into the sleeve, rendering it useless.

It fits perfectly to the back of the cyclist, which in long routes does not cause the appearing of pains in the lumbar zone. Besides, it fits in an amazing way to the contour of the body, which attached to the zippers, handles and other fastening elements of the backpack, makes that carrying it results very natural and not uncomfortable (unlike conventional backpacks).

Camelbak. It is the brand for antonomasia for these products, not only because it is the most popular, but because it is the one who offers more variety.

Nowadays, and even more, there are many brands that work in this field (Poc, Evoc, Scott, Osprey, Mavic, Zefal, Fox, Shimano, B'Twin, etc.) giving excellent results, but the one who really continues winning is Camelback. It is the most famous, the most widespread in stores and also the most used nowadays. I'm not suggesting you to buy a hydration backpacks for cycling from this brand, but if you don't know this market really well; this is a very good starting point.
