The sage/khaki Discovery: Large Photo/Laptop Daypack from Tenba is a rough and tough entry into the world of photo/laptop packs. Lightweight and strong, it is designed to hold a bevy of gear safely and securely while providing a way to organize that gear in an easy to access way.
Rated to hold 1-2 DSLRs, 4-6 extra lenses, flash and numerous accessories, it also holds a 15" (38.1cm) laptop in its own rear padded compartment. The bag is basically divided in half with the bottom half being for your gear that is held in a removable, pop out compartment. The top half is for all the extras like a small jacket, books, or even your lunch. The top half is even designed in a slanted fashion to provide for easier access.
The exterior is a tough, water-repellent nylon that is supported by a rapidly deployed rain cover for those moments when you're caught in the rain or snow. The bottom of the bag has a waterproof bottom panel that protects the bag for when you place it on the ground.
Carry it around by its fully adjustable backpack straps and waist belt that make toting this pack a pleasure. There's even a top carry handle for those times when you have to grab it out of the back seat of your car or out of the closet it's stored in. All the zippers are self-healing.
The two sides of the pack have pull-out airline-style mesh pockets perfect for stashing water bottles and other quick access items. The front accessory pocket is perfect for holding your MP3 player or iPhone. There's also a handy ID pocket for your business card or address label.
