Osprey Seral Waist Pack

The perfect trail companion for riders seeking a low-profile lumbar pack with integrated hydration is the 4-liter Seral. Featuring the next-gen 1.5-liter Hydraulics reservoir with a high-strength magnetic coupling for improved hose management, even in rough terrain, this slim waist pack has enough storage capacity for essential ride items like a spare tube, CO2, multi-tool, and snacks. For those who prefer off-the-back hydration carry and the minimalism of a lumbar pack, our bike-specific angled hipbelt and compression straps ensure stability and comfort with a close-to-body fit.

The Seral also includes a dedicated hydration compartment that stores the Hydraulics LT 1.5 L Lumbar Reservoir, perfect for short to medium rides, and compresses for stable carry. With bluesign approved main body and bottom fabrics, GRS-certified 100% recycled materials, all DWR treatments made without PFAS, and a BPA-free reservoir, the Seral is not only functional but environmentally friendly.

To provide maximum stability, the Seral features an AirScape backpanel with contouring lumbar wrap. This design ensures that the pack stays in place even during the most challenging rides. Upgrade your trail experience with the Seral lumbar pack and enjoy convenient hydration and storage on all your adventures.
