“Osprey Seral 4L Biking Waist Pack with Hydraulics Reservoir, Dustmoss Green”

Look no further than the Seral 4 if you are a rider in search of a low-profile lumbar pack with integrated hydration. This sleek waistpack comes equipped with a 1.5-liter bladder that features our updated high-strength magnetic coupling, ensuring improved hose management even in rough terrain. The Seral 4 is designed with enough storage capacity for all your ride essentials, including a spare tube, CO2, multi-tool, and, of course, snacks.

To provide stability and comfort, particularly in keeping the pack close to your body, we have included a bike-specific, angled hipbelt and compression straps. Our breathable airmesh wrap hipbelt contours over the hipbone, while Osprey's ErgoPull cross-body waist strap closure system pulls the pack into the lumbar and side compression straps bring the load close to your body. This results in the most comfortable, secure, and stable carry for riders.

The Seral 4 is purpose-built for riders who require hydration or gear storage while riding and prefer the off-the-back carry and minimalism offered by lumbar packs. It is constructed with PFC-free recycled bluesign®-approved nylon, ensuring a sustainable and durable build that can endure years of riding.

The pack's premium efficiency and design make it an ideal choice for riders. Its storage is tuned to each season, while the ErgoPull waist strap closure system allows for a proper, snug, and stable fit, providing the most comfortable and secure carrying experience for riders during their explorations.
