The playful ATV twin product description The Santoku is a playfully flexing, experimental ATV (all-terrain vehicle) snowboard and the idea of world-class backcountry snowboarder Elias Elhardt. The Santoku is designed to be the most fun and enjoyable snowboard you can have under your feet - no matter where you are on the mountain. In deep snow, it shines with additional buoyancy thanks to the exaggerated nose and tail length. The Santoku's flex and twin shape are so versatile that even park stylers have made it their preferred board. It's hard to match this board to a category because it works everywhere.
