I was looking for a backpack that was different from the norm, yet had a large capacity. This fit the bill perfectly.  The construction seems to be durable. I bike a lot and carry all kinds of things, and this bag holds the loads comfortably. Nice attention to details, such as the side pockets closer snap is actually magnetic, useful and simple to use.  My only nitpick would be the pockets inside the bag should have a flap or zipper to keep little items from falling out.
