Every good bag needs a wing-bag. The Field Pouch is an expanding pouch for cords, accessories, batteries, hard drives, and even mirrorless cameras and lenses. Keep it in your bag, wear it on your belt or attach any Peak Design strap to turn The Field Pouch into an ultralight sling bag. With an expandable roll-top design, a waxed outer shell and felt inner padding, The Field Pouch can safely hold and organize all of your odds and ends. It also includes an attachment point for Capture, making it an ideal bag for carrying mirrorless setups.
