For those on the fence with trying the Levity- I got bamboozled into ordering a small Levity from REI(sales guy said Osprey did not make a medium, when in fact its REI not offering it for whatever reason). So I’m speaking based on actually carrying one…for my old/skinny/paunchy body its by FAR the most comfortable, best fitting(at the hips) pack I’ve tried. I’m a huge fan of the AIRSPEED suspension so I have a Stratos 50 and 2017 Exos 58 and liking my comfort and gizmos, I carry a good 35lbs. The Levity put the weight on my hips, almost without needing the belt, so the belt did not need to be tight nor does it feel at all under padded or sized if tightened up. I attribute the hip thing to the fact that the (keep in mind its a small, but I wear a medium) frame is 4″ wider(at the bottom) than my Stratos and 3″ wider than my Exos. This seems to allow more wrap around and less pressure with NO pressure points or seams to chafe.
As to the rest of the pack…being a small the strap padding was too high up to be as comfortable as it could be with a proper fit but still with the balance and hip loading the straps were fairly comfortable. It loads wide and low….to the tune of 20″ with double drink bottle on each side. The side pockets are stupid large and have forward facing exits plus top exits, the forward ones can be tied off to the frame to prevent unwanted bottle/gear ejections.The top edges of the side pockets have string loops that could be used for tethers or such.
The lid/brain is a nice size and works better than the Exos lid for oversized loads, but lacks the underside pocket. The lack of pole straps, belt pockets etc really kill my total love of the suspension…and I admit the Stratos totally spoils me by having instant zip open access to 12 areas but at 50L its also just too small(and a bit porky). The Exos is middle ground, a couple useful pockets, external hanging loops, but no improvement in comfort over the now ancient Stratos design.
