Teufelberger Braided Safety Blue Ultra-Vee is the industry standard 16-strand climbing rope. Each strand is comprised of tightly plied fibrillated polyolefin fibers.
This fiber makes the rope softer and more flexible which translates into a rope with superior knotability, better handling and no "memory". The rope coils nicely and does not kink after it's untied.
The entire rope is coated with a protective finish to enhance abrasion resistance. Blue safety core yarns act as a warning flag should rope become heavily abraded or cut.
