I've got two of them, the small (34L) and the large 58L.
These are my go-to lightweight framed packs. The 58 is especially good for a large bulky load and it has lots of useful features. I recently used it for my trip on the Heysen trail from Victor Harbor to Mylor in SA carrying 5 days supplies and hammock camping kit. Robust for the weight and comfortable with that load (about 14kg)
I used the 34 lightly loaded recently on the Sea to Summit. I actually dragged out an older, smaller Osprey pack to use but when I weighed them the 34 was lighter than the older model Stratos 24L.

The Exos cinched down neatly and carried like it was not there. It just had a water bladder, jacket, first aid kit and snacks in it. I have noticed some of the foam in the shoulder straps of the 34 is starting to deteriorate, and also the 34 does not get the better hipbelt like the larger sizes (or perhaps it does now, mine is a couple of years old now)
The hipbelt buckle on both packs is a bit on the small side. I've replaced the buckle on one of them with a larger version (easy to do, no sewing required) Both packs have the usual Osprey excess straps issue, which can be solved with scissors.
