This is a black/green/red Heavy NATO watch strap offered in 3-ring or 5-ring for secure attachment to the wrist. Our Premium Heavy NATO is made with a durable nylon material giving a tough look, but not at the expense of comfort. Although these are much more thick than our Classic NATO straps, they still maintain the comfortable feeling expected with a NATO strap. Not only is this constructed with heat-sealed ends, but also is made with stitched lining for an extra layer of protection. This is a perfect companion product for the larger watch.
