CAMELBAK MARATHONER 2L Hydration Pack

The Marathoner™ is for the runner who wants a low-profile solution and minimalist storage. Our best-selling vest carries 2 liters of water for runs of 2 hours or more—and its air mesh panels keep things light and breathable. We've also added compartments on the shoulder harnesses so you can access your essentials without slowing down: a sweat-proof compartment for your phone, a stretch-mesh envelope pocket for gels, and storage for two extra water bottles. Above all, we've designed this pack to fit comfortably without bumping around. We've added dual sternum straps for more stability, and made the top strap elastic for a snug fit that won’t restrict your breathing. And thanks to the adjustable harness and drawstring compartments, you can cinch both the pack and reservoir down as your load gets lighter.
