I have a Lowepro backpack in very clean condition with minimal wear. All zippers are intact, no rips or tears. Very clean, from a non smoking home.
Interior dimensions: 6" deep, 13" wide and 18" tall
I have a Mountainsmith camera bag, used indoors only in a non smoking environment. Interior dimensions are: 8.5" deep, 10.5" front to back and 20" side to side with plenty of side top and flap pockets.
