The Beal Opera 8.5mm Dry Cover is a top spec triple-certified climbing rope for advanced sport climbing, ice climbing and mountaineering in mild to moderate weather conditions. The Beal Opera 8.5mm Dry Cover is rated as a single, twin and double rope and offers on-point handling, minimal sheath slippage and superb weather protection thanks to Beal's unique Unicore construction and Dry Cover treatment. A little cheaper than the Opera Golden Dry, this rope is ideal for climbers who don't want to be climbing in extreme weather conditions, but still want the performance and handling of a treated rope; the Opera is also one of the lightest triple-certified ropes on the market, weighing in at only 48g per metre and making it a true multi-discipline rope for the expert climber.
