Description
The Osprey Seral 4 Lumbar Pack in Raven Black is designed for those seeking a minimalist alternative to traditional over-the-shoulder packs. It includes a 1.5L Hydraulics lumbar reservoir stored in a dedicated hydration compartment that compresses for stable carry. A magnetic hose attachment keeps the bite valve easily accessible. The pack features a zippered main compartment with internal tool organization and dual zippered hip belt pockets. A front panel bungee allows for carrying extra clothing. The reservoir compartment has direct zip access. The pack uses extra thick ridged foam with a center air channel for ventilation, and an Airmesh wrap hip belt with zippered fabric pockets provides both stability and breathability.
Warning: The high energy magnet may affect electronic devices such as pacemakers or avalanche beacons. It poses a swallowing hazard and is not suitable for children under four years old. Refer to the Osprey Hydraulics Owner’s Manual for further information.
