Carry the essentials without weighing yourself down.

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.

Comfortable, snug little day pack!

  • Familiarity:I gave it as a gift but have feedback to share

I bought this for my boyfriend for his birthday because his old hydration pack was difficult to put water into and the seal kept coming off. It also didn't hold more than a set of keys and a cell phone, and I ended up carrying our snacks and food.

This pack has a lot of room for lunch/snacks/extras and the water reservoir slides in and out easily from the pack itself. Something I wish my own pack could do. Essentially, he does a lot of running and needed something to fit closely to his body that wouldn't annoy him while running up and down mountains. This does just that! He can now also carry his fair share of the food ;)
