The SKYLAKE GREEN series features our advanced Fused Laminate Construction, dual texture deck pad, enhanced dynamic rail, and permanent unbreakable fins.

If you don’t know which board to get, the 10-7 GREEN is a great place to start.  It does everything extremely well and just feels right.  You can shift up to the 10-9 or down to the 9-6 depending on your weight and height and enjoy the same level of performance.
