Octane 12 Fusion 2L Hydration Pack combines ultralight comfort with versatile trail storage
What Our Gearhead® Experts Are Saying:
"This pack hits the sweet spot for quick mountain missions and half-day hikes. The fit is snug and stable, and the new Fusion reservoir is the lightest and easiest system I’ve used. I love that it carries trekking poles and still feels minimal. Total go-to when I want to move fast and pack smart."
The Octane 12 Fusion 2L Hydration Pack doesn’t do limitations. Whether we’re charging up a ridgeline or running ridgelines between alpine lakes, this ultralight pack keeps us moving with everything we need close at hand. At just over a pound, it delivers big performance without weighing us down.
With 10 liters of compressible cargo space and a new 2-liter Fusion™ reservoir, it’s built for hydration and efficiency. The 3D Vent Mesh back panel boosts airflow, keeping us cool when the pace picks up, while adjustable sternum straps fine-tune the fit on the fly. Side stretch pockets, a Command Center harness, and multiple gear stashes make it easy to stay organized, even when the trail isn’t. This is the fast-and-light pack for days when the goal is to go farther, faster, and freer.
