*Specially made 100 oz. Nalgene bladder is specially made for the Hydraulic series and makes up the frame of the pack.
*Suspension system is amazing
*Back-panel mesh offers amazing breathability
*Works as well on a bike as it does for a daypack.
* Pack comes in 3 sizes, S, M, and L; This review is for a medium.
|*Price-$139 @ REI is pretty high for a daypack. Even with the lightest UL gear, you'd be hard pressed to turn it into an overnight pack.|
*Hipbelt somewhat small
