WHISTLER HD EXTRA SOFT 32This nylon poly blend four strand rope has a small size yet is incredibly durable. Designed for high performance in all weather conditions, it provides consistency in both cold and hot environments. With a nice amount of tip weight, it is also a great choice for use indoor as well as in windy outdoor conditions.
