Last week, I received the Think Tank Photo Airport Essentials, the smallest camera backpack of Think Thank Photo’s Airport series. For two years, I have been using the Think Tank Photo Airport Commuter backpack for my travels and I have been extremely happy with that purchase. As I started looking recently for something a bit smaller to accomodate my equipment for short journeys or urban photography, my obvious choice fell on the smallest backpack of Airport series. Here’s my review on my latest camera bag purchase. The Airport Essentials backpack comes in the usual Think Tank Photo’s elegant black exterior design with minimal visible features and straps.
