Two patents, one product . . . the Matrix Gyro Rewind Vi Ferrata Set is the absolute best in class with the patented Gyro system to eliminate twisting and tangling with three independently rotating swivels and the patented Matrix shock absorber. The lanyards use special elasticized 22 mm Rewind webbing that compacts to a shortened length to stay out of the way while climbing, but extends effortlessly to full length for passing anchors or straying from fixed lines. Connects to any harness with a twist ring of Dyneema that positions the unit in its upright position even when passed through vertical tie-in points. Equipped with two Hercules squeeze-activated carabiners.
