The Ultra 10 was designed to endure one of the toughest trail races on earth: the Ultra Trail du Mont Blanc. This year, our most rugged vest gets an upgrade with even lighter materials and a 2-liter reservoir that delivers more water with every sip. This pack is designed for self-supported runs that take competitors through mountainous terrain and unpredictable weather. It’s engineered to hold everything on the UTMB packing list, including food, shed layers, a headlamp, trekking poles, maps and more. The custom-fit harness and dual sternum straps adjust for a stable, comfortable fit, and the cargo compression lets you cinch everything down to minimize bulk.


  • The brand new Crux delivers 20% more water per sip, with an ergonomic handle for easier refilling, and an on/off lever that makes it easy to prevent leaks.
  • 3D Ventilated mesh offers multi-directional air flow and cushioning to maximize comfort and breathability
  • Secure phone pocket conveniently located for quick access and includes a zipper closure for added security
  • Dual adjustable sternum straps increases stability and offer a range of adjustments for customization
  • Stretch overflow pocket offers easy access to toss in a rain shell or stash extra gear
  • Harness storage for all your run essentials offers organization for fuel and gear, including specially designed Quick Stow flask pockets
  • Reflectivity on front and back for early morning or evening runs

Rated 1 out of 5 by from Slipping straps I bought this four days ago and i'm - so unhappy. I fill the reservoar, take some food, fit (coustomize) bag to my body. And set out on small (40km) trip. Troubles start early. The (both - flexible and upper) straps on the front chest - releases. I readjust it, but releases again. And again. Ok, i fix it by knot. Its not ideal. Then start slipping remaining - side straps (on hip). While running, their requiring constant readjustment. The straps slipping and slipping and slipping. Every 5 minutes must be readjustet. Its horrible! Pockets and rest of bag is fine. Product cant be recomended. Maybe for walk :( Its fail. -- And - is some way to fix this problem? Any guide? Else i must return bag to vendor.

Rated 3 out of 5 by from Too many trade-offs to save a few grams! I had a high expectations in this new ultra vest by Camelbak! I own and use the previous Ultra 10 model (electric blue and yellow) regularly for my training and ultra races. The new Ultra 10 definitely has some improvements compared to the previous model: - organization is top notch: I love the different mesh and zip pockets they have added - the phone pocket has is bigger and easier to open - the zip pulls are easier to find and use - the front harness water bottle pockets are deeper - It is lighter than the previous one - it offers improved breathability compared to the prevoous model I have to be honest: there is quite a few things they did get right with this pack. Unfortunately, the drive to reduce weight - and probably cost - in my opinion has resulted into excessive compromise and flaws were introduced compared to the previous version! The negative: - The chest and side straps do not stay in place and the pack needs to be constantly readjusted: it becomes extremely annoying, much more so considering it is a running pack that is supposed to be used for ultra distanaces. - Adjustability has been considerably reduced compared to the previous version: it will fit some but not others! - The back panel is not as comfortable as the previous model: less padding. - The shoulder straps are not as comfortable as the previous model: it can be fine for shorter training runs but in an ultra where mandatory gear brings up the weight or need to carry a full reservoir, it becomes uncomfortable - The reservoir can be removed and inserted only sideways: it's fairly quick but personally preferred the previous model; - There is no way to sinch or keep the gear in the pack from moving around. The mesh pockets inside the pack can help for some smaller item but you can feel stuff bouncing around if not full - The back design is awkward as it's deep and narrow: making it slightly wider and longer and less deep would have made the pack hug your back more closely and bounce around less - The pole attachment system is very basic to say the least: on the previous model it wasn't good either and they haven't improved on it. You are supposed to stick foldanble poles into your left pocket and secure both poles using an elastic loop at the top. It works but creates an imbalance and the poles move around too in the side pocket. - Mesh material is the thinnest I have seen: sure it reduces the weight by a few grams but also means it's way less durable. I would use this pack only if it fits your body type fine and you don't need to carry much gear. It could be a good pack for warm weather training or ultra running where you don't need to carry heavier extra layer or gear. If you don't have minimalist gear, I wouldn't use for the UTMB as it would be too unfortable or even too small to fit everything! The fact that you have to costantly readjust the chest and side straps is a major oversight in design. Too much focus on saving weight at the expense of comfort and important feature such as compressing the pack and adjustability!

Rated 1 out of 5 by from Legit the worst thing ever Look up the 2016 models people are reselling them for 100 more than they were bought for these are garbage the mesh will fall apart if your running through the woods honestly just bring the 2016 back with a larger front pocket that will fit plus size phones the durability was 1000% better on the old one the new one has NO adjustability with front staps AGAIN BIG downgrad

Rated 1 out of 5 by from Straps constantly come loose! This pack would be awesome except for the straps constantly needing to be tightened. Wore it for a ten mile run and had to re-tighten/cinch the straps every two minutes. By the end of an hour+ run this became extremely annoying. The rest of the pack is great but nothing could possibly make up for what the straps are lacking.

Rated 4 out of 5 by from Light weight & comfortable I love this vest mostly because it is so comfortable. Lots of pockets and storage space which is great for me during my long distance paddles. And it has a whistle which is required for competition. The only thing a miss is a holder for the water tube, I like to have the mouth piece close to my mouth so I don't miss a stroke. I'll be able to rig something up. Also, the chest & side strap are going to get stretch out because there is not much to them, but I really don't need them so it might not be a problem.

Rated 5 out of 5 by from Best Camelbak model ever. One huge 2-liter hydration bag. Over ten pockets. Lightweight technology. Two big pockets on the front straps. Best practical backpack. Ever.

Rated 2 out of 5 by from Good size and balance but straps loosen Good looking pack and the size is just right for moderate to long training runs. Like many others though, I find the straps continually loosen and have to be readjusted. One remedy I’ve used that helps just a bit is to rub wax on the straps (think waxed skate laces) but this isn’t fully reliable. Too bad - my older packs, e.g. Marathoner, never had this problem.

Rated 3 out of 5 by from Too big The front side pocket are great, but overall the vest is too big. The rear pocket must be reduced to reduce the size of the vest.
