Note: Has some white details. This new version of the Kentaur Ithaka has a monoflap (single flap) with the knee roll sitting on the flap, providing the rider with optimal support. The saddle is made of double calf leather and has a white welt (piping) along the seat and on the back of the cantle. The difference between the Ithaka AP and the Ithaka APK is that the APK has a shorter roll. This makes it better suited for riders with longer legs, riders who prefer a more chair-like position, and riders who don't like being completely confined but do appreciate having a roll in case their horse makes an odd movement.
