In reply to wookie667:
My partner has one, and hasn't had it long enough to provide in depth comment. Light, comfortable to carry, but the back system does have the propensity to 'ruck' above the waist belt if not fully loaded; this doesn't appear to cause my partner problems (though might for others). Roll top works well for access. Shoulder strap mesh pockets are gimmicks, but the side mesh pockets work well, hip belt pockets are a lot smaller than you might expect.
Overall a bit on the bulky side to 'run' with but fine for 'swift' backpacking.
Comes in two back lengths so be sure to test both to see which suits.
