The rope that made us famous, BlueWater II Plus, is the standard for use in caving, rapelling and rescue applications.  Its design of double twist cabled sheath strands as well as double twist cabled core strands is truly the most unique and exacting rope design anywhere.  These factors make it the best all around choice in a static/low elongation rope.
