The slate gray Photo Hatchback 22L AW Backpack from Lowepro is an excellent choice for a day out in the field, walk along the boardwalk with the family or even a quick down and dirty gig. It's designed to hold your DSLR with an 18-105mm lens attached and two or three additional moderately sized lenses, flash, accessories as well as your iPad or tablet held safely within its own dedicated compartment.
The "wow" feature of this bag is that it comes with a removable camera box which, when removed, turns the pack into a full-fledged, empty pack that can be used as a daypack. The camera box comes with a storm flap for protection and two handles for easy removal. Load it beforehand, place it in the pack, and you're off. And, on days when you don't need it, just lift it out and the pack is ready for clothes, books, food, jacket or groceries.
Access is via a top loading zippered opening or its very handy side "hatch" for rapid retrieval of your camera when the shot appears. All the zippers are YKK for added durability. The 2.1 lb pack is comfortable with its adjustable backpack straps. This is an outdoor pack that is prepared for all weather eventualities since it contains Lowepro's All-Weather cover that can be rapidly deployed when the weather turns against you. The Photo Hatchback is made from strong 600D polyester and 210D nylon ripstop polyurethane-a combination made for the outdoor enthusiast.
