Osprey Seral 7 Lumbar Hydration Pack

For riders who prefer an off-the-back hydration solution over traditional over-the-shoulder packs, the Osprey Seral 7 is the ideal lumbar hydration pack. With 7 litres of storage and an included 1.5-litre Hydraulics™ Lumbar Reservoir, it provides ample space for essentials like a spare tube, patch kit, CO2 inflator, and tools.

Designed for stability and comfort, the AirScape™ backpanel contours to your lower back, while the angled hipbelt and compression straps pull the pack close to your body for a secure fit, even on technical terrain.
