The Story
Originally developed as a modern military backpack, the A-III Pack has earned its reputation as one of the most refined and functional pack designs ever produced. Its clean proportions, smart pocket layout, and balanced structure have made it a reference point for designers worldwide, long after its initial military use.
Post O’Alls’ connection to the A-III Pack runs deep, dating back to the late 1990s when the brand first sourced the bag from Eagle Industries before continuing production with Ballistics Industries in Japan. This season’s special order revives that collaboration using lightweight nylon ripstop, chosen specifically for everyday city use while maintaining the durability and intent of the original design. Finished in Post O’Alls’ core navy color, it delivers a rare blend of military heritage, Japanese manufacturing precision, and practical modern wearability.
