The CSI jump rope features a 16-foot long cotton rope and smooth wooden handles for a nice easy grip. The cotton rope is made of heavy weight cotton that is 5/16-inch in diameter; so it is made to last and outlast other jump ropes, no matter what surface you use it on. The wood handles offer a much better grip when doing serious jump rope workouts. Try it over our competitors and we guarantee the lowest price. You will love this CSI jumprope.
