The Cobra II Unicore by Beal is a great classic for adventure climbing. Light and free-running for ease of use on long routes, on the crag and in the Alps. Technical and robust enough to sustain the most difficult loadings, it now benefits from all the advantages of the Unicore technology.
The Unicore process joins the rope core to the sheath without affecting handling or flexibility. This eliminates slip even in the worst conditions. If the sheath becomes torn or cut, the core and sheath will remain bonded so that the climber can pass the damaged section and doesn't become stuck.
