A: the harness works well.. but is a little snug to fit. there is no padding- this includes lower back, but it really doesn't engage lower back.. it presses against the upper part of the back (although, i'm 6'2 .. so maybe it rests differently if you're shorter). it's hard against one's back, but i've never felt any ill effects. i've climbed up steep/ long staircases in indonesia, had it on my back on a scooter.. it's served its purpose well. i was concerned about its durability from reviews but have found no issues. i recommend it.
