Like the original, but for the modern skier, the Marker Duke PT 13 Ski Binding takes reliable retention and brings it to the backcountry. The unique toe on this binding pulls double duty as a pin binding on the ascent and an alpine binding on the descent so that we can do it all. The max DIN of 13 makes this the lighter and more forgiving of the Duke PT's, allowing it to thrive on the feet of lightweight or newer backcountry skiers.
