Gregory changed their design on this pack. The previous version of the Z35 was a panel loader and was better for commuting to work and back. This pack, although it is the same size, is a top loader with a rain flap, cinch cord and cinch strap. The extra cord and buckle make it a little less conveinant to get things into and out of the pack. It is still a great pack, I just didn't know they changed
