Colorado Mountain School Gear Review no rating given just a review

Although it is unrealistic to expect any one rope to perform well in all of these categories, the Sterling Evolution Aero 9.2mm dynamic rope does a fine job of rising up to the challenge.  Straight out of the box, the Evolution Aero, with its DryCore and DryCoat treatment, shined in ice-climbing, alpine climbing, and mixed climbing across the winter freezes of Colorado.  As the summer climbing season drew on, the same rope was my top choice for multi-pitch rock routes, alpine climbs, and sending sport projects.  From steep alpine cracks of The Diamond to big-wall free climbs in Zion to the overhanging limestone of Rifle, the Aero had an excellent handle and feel that was comforting when making difficult clips.  During falls, the Aero gave a great catch and was easy to hold, inspiring confidence when logging in airtime working a project.
