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.
