Osprey Seral 7L Unisex Biking Waist Pack with Hydraulics Reservoir

The Seral 7 Lumbar Pack is designed to provide a comfortable and stable off-the-back hydration and gear storage solution for riders. Featuring a number of innovative design elements, this pack offers excellent ventilation, fit, and organization.

At the heart of the Seral 7 is an extra thick, ridged foam backpanel with a center air channel. This AirScape design contours to the lumbar region, providing maximum stability and support. The backpanel is wrapped in breathable AirMesh, which, combined with the hipbelt, creates a stable and ventilated carry.

The hipbelt on the Seral 7 is a key component, designed to keep the pack secure and close to the body. It features an AirMesh wrap that conforms to the hips, with zippered fabric pockets for storage. Osprey's ErgoPull waist strap closure system allows for a snug, stable fit by pulling the pack into the lumbar region.

For added stability, the Seral 7 also incorporates side compression straps that pull the load close to the body. This integrated compression system, combined with the contoured hipbelt, ensures a secure and comfortable carry, even over technical terrain.

Hydration is a key capability of the Seral 7, with a dedicated compartment that houses a included 1.5L lumbar reservoir. The reservoir's hose attaches to a magnetic bite valve on the hipbelt, providing easy access to hydration while riding. The reservoir compartment also compresses the pack for a stable carry.

Beyond hydration, the Seral 7 offers ample storage and organization. The main compartment features tool organization and an internal zippered pocket. The hipbelt also includes zippered pockets, perfect for storing essentials like a spare tube, patch kit, or CO2 inflator.

Constructed with PFC-free, bluesign®-approved recycled nylon, the Seral 7 is built to be tough and durable, able to withstand the demands of mountain biking. This sustainable construction underscores Osprey's commitment to the environment.

Whether you prefer an off-the-back hydration solution or simply want a minimalist pack for riding, the Seral 7 Lumbar Pack provides the perfect balance of comfort, stability, and functionality. Its innovative design and features make it an excellent choice for mountain bikers seeking a reliable and versatile storage solution.
