roger nielsenwrote a review of Gregory Z 55 Backpack - 3112-3722cu in on May 18, 2011
Bought one last August for the comfortable suspension, though I knew the poorly designed sternum strap would cause problems (as it did on my Pyr dayback). Fixed the sternum strap it so it stopped riding up, but nine months after getting the pack the cheap clip holding the sternum strap to the left shoulder strap popped off.
Ordered a new pack as a replacement but, factory fresh out of the box, found stitching in the upper back part unraveling between where the shoulder straps are sewn in. No reply to my messages to Gregory customer service, so I'm firing Gregory and switching to Osprey.
