"The TX series is the alpine touring-specific line from Kastle, designed with their guide team. They enjoy many of the same features as other Kastle models but boast an ultralight core that will have you beating everyone to the top of the skin track. The TX87 is fully traditional camber with no rocker element like the TX97. This is an excellent ski for busting through the backcountry crud. The core uses Karuba wood for maximimum strength-to-weight performance. You get a ski that is lightweight underfoot, snappy in turns, and damp enough for charging through a variety of snow conditions. Like all Kastle skis, the TX has Hollowtech in the tips reducing swing weight. Sandwich Cap construction provides the ideal balance of the high-end durability and edge performance of sandwich construction with the lightweight benefit of cap construction. Notice the handy notch in the tail for quick skin attachment. The Marker Baron bindings are a burly, durable, do-anything touring binding that can also handle daily use at a resort. Happy exploring."
