They are a vynal coating webbing they are extremly durable I have some that are 5 years old.  The work great for a field check cord, tracking lead and obedince. The float on the water and don’t absorbe water like other leads. They rol up very neatly and are easy to clean. They can be made in any length 2.45 per foot. We recommend 15ft. For field work and an eight for obedience we can accept visa or master card.
