COMFORT
The Osprey Rev 18 has above average comfort, deriving from multiple elasticized straps that provide a wrap-around feel. There are also anatomically shaped shoulder straps to disperse weight across the back and shoulder. The pack also carries heft nicely at the middle of back, which helps position the bulk onto the hips. 

STABILITY IN MOTION
The strap system gets a B+ for preventing bounce. It’s very secure, even with carrying up to twenty pounds of payload. With twelve securing straps, it has potential to be almost custom fit.

WEIGHT
This pack is exceptionally light weight. Without frames or heavy padding, the weight is kept down without sacrificing function. 

QUALITY OF CONSTRUCTION
The nylon material, making up most of the pack paneling, is strong, durable, and attractive. However, strap ends are way too long for the average sized runner, and there are many of them without hold-downs, causing too many loose ends.

MULTI-SPORT VERSATILITY
The Osprey Rev 18 succeeds as a multi-sport pack, used during outings with good conditions.  It isn’t water resistant, except for the Digi-Flip phone pouch. However with many convenient features, gear holding spaces, and a well-designed fit, the pack can excel in most activities.
