Used only indoors for a couple months. Only very minor flaws pictured — a small pin hole where I placed a pin and the metal on the zippers changed a bit with time. Does not affect functionality as all of the zippers and buckles work perfectly. The back of the backpack is still firm and holding it’s shape as I didn’t use it often. Open to offers! Originally $89.
