Prefer an off-the-back hydration solution instead of an over-the-shoulder pack? The Osprey Seral 7 lumbar pack was made for you. 1.5 liters of crystal-clear water power take your ride from good to great, making your mid-ride pit stops truly worth it.

Featuring an included 1.5-liter lumbar reservoir and magnetic bite valve that attaches to the hipbelt for easy access. Some lumbar packs have a tendency to creep around while you ride, but this one won't. Compression straps pull the pack into your lower back and wrap around your hips for supreme stability, even over technical terrain. A zippered main compartment and hipbelt pockets fit your spare tube, patch kit, CO2 inflator, and more.

Many features take the Osprey Seral 7 Lumbar Hydration Pack above the pack. Features like the AirScape back panel and the angled hip belt deliver powerful security, providing ultimate stability while on your ride. The next time adventure comes calling, take your lumbar water waist pack and hit the trail.
