The R6 Field Pack allows for the secure and simple attachment of weatherproof accessories to the exterior of the bag. The patented Arkiv® modular system gives the bag freedom to evolve and adapt as needed. The pack can be used in either \"roll-top\" mode, or in a traditional \"flap-down\" configuration, has one external zippered pocket for items like a phone or passport, and one interior zippered pocket that is ideal for documents and fits up to a 15\'\' laptop. The Arkiv backpacks feature multiple weatherproof compartments, urethane coated YKK zippers, waterproof materials, and an internal frame sheet.
