Sand Viper Dune Board
The Sand Viper lets you carve out turns on a the dry mountains of the desert when the winter snows dry up.
There are a few design changes, though, to compensate for the difference between sand grains and snow flakes. Namely a wider snout to coast over the imperfections and a very narrow tail to dig into the heavier sand allowing you to turn. Check it out.
