I've taken this for a couple of dayhikes and an overnighter and it had held up so far. I purchased this primarily for hikes, and what I like about the concept of a compact assault pack is the high degree of configurability.
On it's own, this pack is "low-profile" enough to be used both for a light hike or a trip to the mall. For extended trips, you can add modular attachments and go up from there.
In my case, a "dayhike/mall/class config" would be the pack on its own. The "overnight config" would be the pack plus the "shelter module" and "sleep system module". The "3D/2N config" would be the pack + "shelter module" + "sleep system module" + "sustainment module 1 and/or 2", and so on.
With regard to the weight-carrying capacity, I have loaded this pack up to 15 kgs with no problems. I've e-mailed Condor with regard to load rating, and they suggested to load it with "at most 50 pounds. "
With regard to how the pack wears, it fits the 5'5" me perfectly. I noticed, however, that for taller guys, this pack would have to sit quite low on your back for you to use the waist strap properly (i. e. resting on top of the hipbone).
The only thing I would have wanted more from this pack would be options for internal organization. However, for this price range, I guess that would be asking too much.
As always, great service from TA.
