Osprey Seral 7

Prefer an off-the-back hydration solution instead of an over-the-shoulder pack? The Seral 7 lumbar pack was made for you. 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,we promise this one wont. 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.
