Josh E.wrote a review of Gregory Z 55 Backpack - 3112-3722cu in on January 18, 2012
Ok so anything you wear on your body is objective in review I believe... I got the large size Z-55. With that said this thing fits me like a glove, I'm 6' 180lbs. The lumbar is in a perfect place for my back. its not the lightest pack I've ever owned but it fits me better, and is a well thought out design. No rain cover but I already had one so it didn't matter to me.
