San Francisco based label MISSIONWORKSHOP is finally unveiling bags equipped with their patent pending Arkiv System. The Field Pack we see here should be first of many, which to integrate the highly functional modular system. Weatherproof materials on the exterior of the bags make this item an all-arounder, for daily use and for traveling. The black vertical strips on the exterior of the bag are the Arkiv System, enabling attachment and detachment of extra compartments in a flash. To see how this adaptive system works in real life, check out the short video below.
