The Airliner is ultra-light, ultra-skinny and is perfect for quick ascents on long pitches. But don’t let Airliner’s small size and light weight fool you. It may be small but it does not sacrifice an ounce of performance. The Airliner has the same durablity that you have come to expect from MAXIM® Dynamic Ropes. All Airliner ropes come standard with the Endura Dry 2x dry treatment. Airliner is dual-certified as both a single and a half rope.
