Why We Like The Osprey Seral 4L Hydration Pack
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.

I grabbed this to wear
[This review was collected as part of a promotion.] I grabbed this to wear at a race versus my backpack so I had more airflow. It fits great and is easy to cinch down to keep it from flopping after drinking some water out. Excellent product. Highly recommend.
