Why a lanyard? Because I'm lazy. I don't have to take it off to remove or add layers of clothing - especially when it decides to be sunny, start to rain, be sunny + muggy, then pour + thunder in one day! We braid these cords with our very own hands. We've attached a flexible, pvc number/card pouch with zip lock closure to keep your number/s dry. The pouch is sized to fit a standard business card [any number card bigger is kinda unneccesary right?].
