An evolution of the original Hadley design, the Hadley Pro integrates additional features for increased practicality and longevity, such as a reinforced hand-strap and the attachment of the shoulder strap to a concealed fibreglass stiffener. It still possesses all the unique and distinctive design elements of its predecessor; combining utility with classic world-traveller styling. To help you organise the bag's contents, the Hadley Pro includes a removable lift-out insert with dividers which is held in pace with Velcro. In addition to the main compartment, two front compartments and a zippered rear document pocket, the Hadley Pro also accepts auxiliary AVEA side-pouches. Billingham recommend the AVEA03 for aesthetic reasons, but the AVEA05 pouches will also fit if you really need the additional room.
