Don't be stubborn - stay hydrated while hauling your gear.

The Camelbak MULE is deservingly one of CamelBak's top sellers and is specifically designed for mountain bikers, but we've found it works splendidly for climbers and skiers alike. The Air Director back panel keeps you cool, while a sternum strap and a removable waistbelt keep the MULE secure on your back. An efficient and compact system, the MULE has 100oz of hydration and smart cargo spaces, complete with internal organizers for tools and small gear. Perfect for any outdoor enthusiast.

Great little pack

This thing has very little space, and I emphasize little, for things other than the water bladder. A very lightweight jacket, a small camera, and a bit of food is all it holds. Not made for hiking but works fine for biking, short hikes, or anything else like that. Great little bag.

This M.U.L.E. Don't Run

I have never been so disappointed with such a well-reviewed product in my life. I am training for a marathon, and have recently entered the "really long training run" phase of typically 17+ miles. Instead of doing water drops along the way, I decided to purchase, a MULE. Made sense. Keeps things simple and elegant. I ran an 18 miler yesterday. The water sack/valve/ mouthpiece apparatus is very fine and worked like a charm. The various pack straps, however, were a horror story. The sternum strap, because of the silly sliding connectors which keep it mated to a vertical cord on the shoulder straps, slid up and became a throat strap when I cinched it. Very tight, very unpleasant and it prevented me from yodeling during my run. The shoulder straps were equally flawed. Approximately every 100 yards they would loosen significantly, and I had to re-cinch them so the pack would stay tight to my shoulders and back. I don't know if it had to do with the shifting water in the bladder or what, but it was getting to me by about mile 2. I intend to return it.

I got this bag as a gift, and I’m very satisfied. Perfect bag for a light day hike. It’s able to hang a light rain jacket off it, and enabled to utilize all the compartments within the bag.

The only downside to it is that it is tough to utilize all 3L of the hydration pack and somehow manage to zip it closed (never was able to fill it all up and was unable to zipper it completely w ease). If it’s filled a lot, it’s hard to use the big zipper pocket cause the hydration takes so much space bulging.

Yet, I don't fill it all the way (3/4 of the hydration at the most), and still am able to use most of the space. I just hang my shirts/jacket off the meshed sections, and stuff real little things in the zippered compartments.

Overall, I’m pleased.

Wear with pride.

What can I say? I've had a Mule for over 6 years and it's still one of my favorites. This is THE classic Camelbak. Always comfortable, just the right size, and totes everything you need.

This pack rules!

The pack fits perfectly. When I go trail running, the only part of the pack that moves is the water inside the three liter bladder. The gear stays tight and the pack doesn't jostle around at all. This is a great product.

LAME instead of MULE

I will keep it short and to the point. First in order to put a full bladder in to the pack you find yourself doing a wicked voodoo dance to get the damn thing in. It is great that it fits so tight but it is a real pain in the seat when you want to fill it. EVERY ride in my case. The other problem is you can’t put anything in the big main compartment because this only amplifies the NO FIT problem. Someone has to product test this stuff so please feel free to tell me how to use my pack because it is going to find a new home in the trash.

CamelBak Mule

I looked at a lot of Hydration Packs before deciding on the MULE. I wanted a pack that was small yet had the ability to hold a little gear. The MULE fits that description very well. Only negative I see is that it has a few too many storage areas/dividers that add a little extra weight to the pack. I would not hesitate to recommend this pack. It has bungee cord tie down that just adds more flexibility when storing clothes.

Keeping the Troops Hydrated

We received word that, for some reason, the US Marines working on the deck of the USS Harry S Truman were not being issued Camelbaks on this deployment. They get extremely dehydrated working on deck in all sorts of weather and heat. Our son is a Corporal serving on the Truman right now as an F-18 jet mechanic. When we heard they weren't issuing Camelbaks, we found in just a few moments online. After comparing their offerings with those of their competitors, we chose We directed that the MULE Camelbak be sent directly to our son. He emailed us from somewhere in the Medeterranian that he got it, and he was DELIGHTED with it. THANK YOU,, from the grateful dad of a thirsty Marine! :O)

Best I've had.

The Mule is an upgrade to a 'broken' hydration system I bought a few years back (valve is shot). To my surprise, it has exceeded all expectations I had when purchasing it. Not only is its 3 L volume handy, but it has an immense storage capacity for such a small pack, and it's comfort, and ease of use make it an extremely good choice. Really have no complaints whatsoever about this solid, and well thought-out pack.

MULE is versatile

This pack rocks, I recommend anyone to buy this for any activity needing hydration. I'm an avid skier, MTBer, hiker, fisherman, and canoe/kayaker; this pack holds all the gear i need for short trips to all day skiing and biking sessions. Pump, snacks, phone, tools, flashlight, holds it all and more!

Mule Hauls

As an avid mountain biker / canoe tripper the mule is great. You can paddle and drink instead of rumaging around trying to find a water bottle that is covered in sand, leeches etc., on the bottom of a canoe. I can stow my paddling shoes, binoculars, sunscreen, bug dope, maps, keys, wallet, snacks and still have room for more. It also fits well while you portage a canoe without getting tangled with the yoke.

Killer on the slopes

The MULE is perhaps the most versatile bag I have ever purchased. I took it snowboarding yesterday, hiking last weekend, and mountain biking last week. Perhaps one of the most valuable pieces of equipment I have owned, with its light weight, numerous pockets for all the "stuff" I usually carry, and max adjustability for best fit.

Camelbak's Mule

The Mule works very well for me. I break and train horses and it is the best way I have found to carry water with me while I work and I have tried a lot of different things. I am very happy with my Mule. Not only does it alow me to carry the water I need on long trail rides but it also is a great place to keep my emergency first-aid supplies, which has come in handy on more than one occasion. The Mule is one of the best products that I have ever purchased.
