The small black Airport Essentials Backpack from Think Tank makes a photographer's life easy since on the outside, it resembles an ordinary piece of luggage while the inside speaks differently. The pack is rated to hold your standard DSLR, 4-6 basic zooms plus your iPad and 13" laptop. It's sized to handle your 300mm f/2.8 so if you're a nature or sports shooter, you're covered. 

Think Tank has designed this bag both for functionality and security since it comes with a security cable and lock that can be tied to a reception hall column or fence leaving you to remove your gear while the rest of the pack stays safely tethered. Even the strong YKK zippered sliders accept user-supplied locks for maximum protection and peace of mind while on the job. Inside, padded movable dividers allow you to arrange the guts of the bag in whatever way you choose. Your computers are stored in their own, separate lockable, zippered compartment. For even more flexibility and security, you can store your optional Artificial Intelligence Laptop case within the computer pocket.

You have multiple ways of carrying the pack from its adjustable harness system and removable waist belt to the very convenient handles situated on three sides. The harness has enhanced lumbar support and air mesh paneling that will help keep you cool while the pack is on your back. And no need to worry about getting caught in bad weather since the pack is supplied with a neat rain cover that stores inside when not needed. A sternum strap is also provided to help maintain balance while walking. The Airport Essentials also accepts Think Tank's optional Pro Speed Belt or Thin Skin Belt that will assist with stability as well as increased load capacity.

Your tripod can be secured to the pack with its feet in a supplied exterior pocket and head tied with a supplied strap. For small accessories, the inside flap has laminated mesh pockets for everything from memory cards to a snack.

The exterior of the pack is made from a combination of ballistic nylon, polyester and nylon webbing all treated for water-resistance. The inside is nylon and polyurethane with padded, closed cell foam dividers. For a small pack that holds this much gear, it's relatively lightweight at a maximum of 3.6 lb. Think Tank backs the Airport Essentials with a lifetime warranty against manufacturer's defects.
