Modern kite cords are more than just any old strings. Technical fibers made of Polyester®, Dacron®, Kevlar® or Dyneema® offer pilots of one-line kites, stunt kites, power kites, and kite sails what they need in terms of tensile strength, expansion characteristics, and durability to perform these versatile sports. Through elaborate processes, the cords are braided, pre-stretched, waterproofed and finished with a protective coat, coiled, and made available in different lengths and tensile strengths
