With the reliability of 13-DIN and free-heel power of an AT binding, the Marker Baron 13 EPF Ski Binding holds you nice and tight on blazing downhills and lets you step and pivot freely on the climb. This year the Baron 13 has EPF, an Extended Power Frame for greater power transmission on fat skis (over 89-millimeter waists). It also got an upgrade to a Triple-Pivot Elite toe and Inter-Pivot heel for secure lockdown when raging down gnarly, no-fall terrain. Both toe and heel absorb energy and provide elasticity to prevent early release. And of course, this big-mountain beast is light and nimble as always.
