Osprey Seral Lightweight Green Running/Lumbar Backpack – One Size

Osprey Seral Hydration Lumbar Pack

Reimagine Lightweight Adventure
Ditch bulky shoulder bags without sacrificing essentials. Engineered for trail runners, fast hikers, and mountain bikers craving hands-free mobility, the Seral lumbar pack delivers smart hydration and gear access where traditional packs fall short.

Core Innovations
– Integrated Hydration: Features our patented Hydraulics™ 1.5L Lumbar Reservoir (included) in a compression-fit compartment—no sloshing or imbalance during dynamic movement.
– Magnetic Convenience: Snap your bite valve securely to the hip belt via high-strength magnets—retrieve it mid-stride without breaking rhythm.
– Optimized Storage:
– Quick-grab main compartment with internal organizers for trail tools
– Dual Airmesh™ hip-belt pockets (zippered) hold snacks/phone
– Expandable front bungee secures jackets or layers

Engineered Comfort
Ventilation isn’t an afterthought. Thick ridged foam padding channels airflow along your spine while the wraparound Airmesh™ belt wicks sweat—even on humid climbs. Direct side-zip access lets you refill the reservoir without unpacking gear.
