Comfort/Adjustability
Easy harness adjustment and standard back panel ventilation keep the Kestrel’s lightweight suspension comfy for most users—unfortunately, those with waists narrower than 32 inches will find that the hipbelt is simply too big.

Stability
Load-lifter straps connect somewhat narrowly to the ¾ perimeter frame, allowing the upper pack to swing around more than expected. Lack of lumbar definition at the back panel was also a stability issue for some testers.

Capacity
The big main compartment is prone to barreling when fully loaded, though using Osprey’s hard-backed Hydraform water reservoir helped to minimize the problem. The external pockets lack the expansion to be useful when the main compartment is full.

Organization/Access
This pack has so many pockets! However, the Kestrel is at its organizational best when carrying a smaller load.

Features
Handy add-ons like Osprey’s Stow-On-The-Go trekking pole attachment and an included rain cover round out a mostly well-built pack. Small issues (plastic zip-pulls breaking in the cold, awkward zips on hipbelt pockets, the non-removable lid) keep it from scoring higher here.

Value
The Kestrel is a good all around value for a variety of recreational hikers.
