Concave tunnel for easy edge changes
Smooth transitions from side to side
Small defined bevels for faster, easier turns
Adjustable ARC fin
With the same shape as the legendary Sixam 2.0, the Siege is incredibly responsive! A tunnel concave makes edge changes effortless, and the ski turns on a dime. A softer flex and increased rocker make this ski feel stable right out of the box and ideal for skiers from beginner to pro levels. The O'Brien Siege is a streamlined ski that's designed to deliver speed and stability. Small defined bevels mean faster, easier turns. Adjustable ARC fin. Pro Wing foil not included.
