Osprey Packs Seral 4L Hydration Pack Aprium Purple, One Size

Osprey's Seral 4L Hydration Pack provides a minimalist design for mountain bikers looking to carry the essentials on short- to medium-length rides. The main compartment houses a 1. 5L hydration reservoir with room to spare for a multitool and a snack or two, while the contoured lumbar wrap delivers a stable, close-to-body fit on varied terrain.
