The Corbie features a robust three-part treatment process. Both the core and sheath fibers are treated with Edelrid’s DryShield treatment, as well as ProShield, which bonds microscopic Teflon particles to the nylon fibers to increase strength and water resistance.
Unlike Americans, climbing ropes are getting skinnier every year. Take, for example, the new breed of ultralight ropes for sport and alpine climbing: the Beal Opera, the Edelrid Corbie and the Mammut Serenity.
With a diameter normally reserved for half ropes, the Opera is the skinniest single- rated rope on the market and the first to break the mythical weight barrier of 50 grams per meter.
