Description
The Osprey Seral 4 Lumbar Pack in Aprium Purple is designed for those who prefer 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 a stable carry. The pack features a magnetic hose attachment on the hip belt for easy access to the bite valve.
Storage options include an easily accessible zippered main compartment with internal tool organization, dual zippered hip belt pockets, and a front panel bungee for carrying extra clothing. There is also a direct access zip path to the reservoir compartment.
Comfort and ventilation are enhanced by extra thick ridged foam with a center air channel and an airmesh wrap hip belt with zippered fabric pockets to provide stability and breathability.
Please note the included magnet may affect electronic devices such as pacemakers or avalanche beacons, and the pack is not suitable for children under four years old. For additional safety information, refer to the Osprey Hydraulics Owner’s Manual.
