The North Atlantic Treaty Organization (NATO) was created in 1949 by the United States, Canada, and several Western European nations to provide collective security against the Soviet Union, and with it the ZULU pass-through strap which is the earliest single pass strap known, originally made in straight cross-weave nylon. We bring back this original design and made it with the most durable and resistant leather around (Shell Cordovan) which is super soft and will patina beautifully over time. We believe this is the ultimate homage to the original design.
