With the same internal size as Billingham's Hadley Small Bag, the new Hadley Small PRO incorporates some features well suited for the professional photographer. The first is the leather top handle, so useful when using the bag as a work briefcase. The second is an extra pocket on the back, with rain zip. And also on the back, a strap to slide the bag through the handle of the suitcase making it easy to travel. Of course, the padded insert made of a dense closed-cell fabric that protects the equipment from knocks on all six sides (also the top). Inside the insert there are two vertical dividers and two horizontal dividers, all of which are repositionable, which are fastened with Velcro. On the outside, the bag is made of three layers of material "Stormblock": two layers of fabric joined together with an inner layer of butyr rubber. Front straps incorporate a quick release system for one-handed operation. The front buckles are only used to adjust the capacity of the pockets to their contents. The Billingham Hadley Small Pro Bag, despite its apparent small size, can hold 2 DSLR cameras, a mirrorless camera and 2 or 3 lenses, plus the accessories and personal items that fit in the different pockets.
