The SIRIUS is the innovative 2-in-1 SUP for white water or wave. Designed to perform in up to Class II white river or small to medium sized waves, it is exceedingly forgiving and easy to ride. Thanks to the 36" wide outline, it's a great board for riding in the rapids and also works extremely well in waves. The Double Rocker line generates lots of power in waves and rivers, but also gives a stable and reactive performance.
