The Terra Twin is designed on the System Camber platform, which features Grip Tech and 3D Fender Technology. It also features Arbor's 3D tip and tail Terra Tech design, which creates a channel for snow to quickly move under and away from your snowboard for reduced resistance and improved speed in deeper snow. When you add those features to it's true twin - wider volume shape which allows riders to size down 3-5cm, it's no wonder it's the board of choice for the backcountry freestyle enthusiast.
