Quick engineering lesson: The 550 paracord (short for parachute cord, naturally) in this lanyard is rated with a breaking strength of 550 pounds. Which, in theory, should be more than enough to handle any everyday carry essentials you need to keep handy. And in practice, we think you'll find this simple design makes quick work of attaching and retrieving your items. No cheap plastic beads here. We use aluminum for extra durability and style.
