Maxim made the Pinnacle Bi Pattern 2X Dry 9. 5mm Climbing Rope for the versatile climber who has mastered ice, mixed, or rock at nearby crags or faraway alpine cirques. An unbelievable performance separates the Pinnacle from most high end, professional grade ropes. The sheath runs smoothly through belay devices and clips into small carabiners with ease. Pair that with Endura Dry's 2x treatment on the core and sheathe, and you can enjoy this rope's solid performance for seasons. Endura Dry 2x decreases water absorption and increases abrasion resistance significantly, so don't be too afraid of iffy weather conditions. The bi pattern has high contrast so it will stay vibrantly noticeable after the rope dirties from extended use.
