They started by updating the back panel and shoulder straps. The hidden passport pocket was made larger and more discreet. They also added a luggage pass-through strap. Other exterior changes include stronger magnets in the carry handles, updated U-pulls for the zippers easier to use key hooks, updated branding, and organization of the Velcro and roller straps on the chin strap. Inside the PRVKE, the fleece-lined pockets have been updated by attaching them to the top compartment access flap and reversing the opening direction so they no longer hang in the way when accessing the top compartment from inside the bag. And finally, the flap that covered the Camera Cube compartment has been removed to allow faster access to your gear. The perfect bag just got more perfect.
