Everyone needs a good side-pouch, and if you think you don't, it's because you've never used The Field Pouch by Peak Design. Featuring an expandable roll-top closure, the Field Pouch is the perfect supplement for your overfilled camera bag; just stuff it with extra cordage, USB drives, memory cards, speeding tickets, and even old-school mirror-less cameras, and leave the heavy hauling to a more frumpy option.
