D3 ION 4 Slalom Water Ski
The D3 ION 4 takes the proven performance of the legendary ION platform and pushes it forward with an all-new carbon layup engineered for faster response and explosive rebound.
While the ION 4 maintains the same trusted mold shape as the ION 3, the internal construction has been completely redesigned. The updated carbon structure creates a more dynamic reaction through the ski, allowing it to load smoothly and then snap back with powerful energy and acceleration as you move through the course.
For skiers who loved the calm, predictable feel of the ION series, the ION 4 keeps that signature balance — but now adds more life under your feet. The ski builds angle easily, carries speed outbound with authority, and rebounds out of the turn with a clean, connected feel that keeps you ahead of the boat.
The large sweet spot and efficient load management make the ION 4 incredibly composed through the wakes, while the new layup gives it the quick response and energy return advanced skiers demand.
The result is a ski that feels balanced, efficient, and confident — with a new level of dynamic performance.
