Great bag for trail running.


  • Fits well
  • Side pockets
  • Whistle
  • Waist belt and sternum strap


  • Sloshing is annoying as hell
  • Bladder hose a little long
  • Side pockets are inaccessible while wearing the pack

I bought this bag for trail runs were there aren't any water sources to refill my waist bottle (w/ Steripen Adventurer). It works well, and stays put on your back but as with any bladder, it sloshes around a lot unless its full, but who wants to carry 3L of water on their back when running a 15 mile trail run climbing 6k feet of vertical... Not me.  

It's made well and carries well on your back, but the sound of water sloshing around kinda ruins the silence and relaxing nature of a trail run, so I tend to leave it at home more than I thought I would. I've tried both burping the bladder to remove all excess air, as well as blowing as hard as I can into the bladder to attempt to pressurize it, and the sloshing is still bad.

I find stuffing a rain jacket into the compartment to kinda take up any extra space can reduce it a little, but only until you drink half the contents, then it's back to sloshing up and down as you run. 


I love the large capacity bladder, but yet it maintains…

I love the large capacity bladder, but yet it maintains a lightweight sleek form about it. I use it during every ultra I run. I also love the detachable hose, makes for easy cleaning.


  • Lightweight
  • Large bladder
  • Plenty of storage for Gu's, food, aid, etc.
  • Detachable hose for easy fill up and cleaning


  • I have found no flaws

I like the weight, shape, and overall design of the pack. Plenty of internal storage and also a place to strap a jacket to on the outside. Very versatile. I can even wear it without a shirt and it doesn't rub or create any hot spots. Good, solid, affordable setup.

The flagship of CamelBak's multi-sport packs, the Octane XCT Hydration Backpack features a unique body-hugging design. A 210-cubic-inch essentials pocket and two cargo pockets on the waist belt offer you enough storage for a full day of your favorite activity. Plan for three hours of well-hydrated running or cycling fueled by CamelBak's three-liter Antidote reservoir. Without water, the Octane doesn't even hit one pound, an ideal choice for those looking to cut any excess weight from their outfit. An Air mesh back panel and the ultra-light 3D Mesh harness allow air currents to relieve your back and chest of stuffiness and over-heating during highly aerobic movement. Complete with a safety whistle and two reflective facets, the Octane XCT provides just that much more confidence when out at night. Season after season, CamelBak's super scientists have been hard at work refining and perfecting the Antidote reservoir, the industry's most popular solution to hydration. At the turn of a cap (a quarter turn to be exact), you can open or close the reservoir, refilling and securing it again in seconds. Center baffling and a sleek design prevent your water from jostling about inside your pack while running, hiking, or hitting the park. When not off exploring the world, simply disconnect the tube using the Quick Link System and hang up the Antidote for proper drying or storage. Since last year, CamelBak's go-to reservoir system has actually lost some weight, reducing bulk in the fill port and offering you that much more convenience.
