Osprey Seral 4L Unisex Biking Waist Pack

The Seral 4 is the ideal low-profile lumbar pack with integrated hydration for riders seeking a minimalist yet practical solution. Featuring a 1.5-liter bladder with an updated high-strength magnetic coupling, this slim waistpack ensures effortless hose management, even in rough terrain.

Designed to accommodate essential ride gear, the Seral 4 offers ample storage capacity for a spare tube, CO2, and a multi-tool, as well as snacks. Its bike-specific, angled hipbelt and compression straps work in tandem to provide exceptional stability and comfort by keeping the pack securely close to the body.

The breathable airmesh wrap hipbelt contours over the hipbone, while Osprey's ErgoPull cross-body waist strap closure system pulls the pack into the lumbar. Additionally, the side compression straps pull the load close to the body, resulting in the most comfortable, secure, and stable carry.

Catering to riders who require hydration or gear storage during their rides, the Seral 4 offers the off-the-back carry and minimalism of a lumbar pack. Constructed with PFC-free recycled bluesign®-approved nylon, this pack boasts a sustainable and durable build to withstand years of riding.

Featuring an extra thick ridged foam with a center air channel, the Seral 4 provides excellent ventilation, while the airmesh wrap hipbelt ensures stability and breathability. The ErgoPull waist strap closure system allows for a proper, snug, and stable fit, and the AirScape backpanel with a contouring lumbar wrap delivers maximum stability.

The dedicated hydration compartment securely stores the included 1.5 L lumbar reservoir, and the hose magnet attaches to the bite valve for easy access while riding. The main compartment offers tool organization and an internal zippered pocket, providing a total volume of 4L.

Overall, the Seral 4 is the perfect companion for riders who require hydration and gear storage without sacrificing the minimalism and off-the-back carry of a lumbar pack. Its thoughtful design, sustainable construction, and exceptional comfort and stability make it a standout choice for those seeking a versatile and reliable riding companion.
