Designed specifically for the climbing wall environment, the thicker sheath associated with the UNICORE process makes for a tougher rope perfectly adapted to resist wear due to repeated belays and low impact falls. The UNICORE process permanently binds the sheath to the core of the rope radically decreasing the occurrence of slippage. Spools ship with end marking kit for tractability. Comes in three colors to help rotation and station identification in your gym. Intended for indoor climbing.
