CamelBak's Octane series are made from ultra-light materials so they’re good for adventure racing, trail running or XC bike riding – anything where you need to move fast and minimize weight.
The Octane XCT takes this approach to extremes by stripping the pack down to the basics. Inside you’ll find our 3 liter Antidote Reservoir, which drops in behind the back panel. Outside we’ve added a single vertical zip storage pocket on the front and two stash pockets on the waist belt and harness so you can keep essentials close at hand. For safety we’ve added reflectivity front and back and a whistle on the harness.
