BLACK DIAMOND

Shop

​DESCRIPTION

This board was designed to bridge the gap between the White Diamond and your standard hi-performance short board.

​This design was made to compliment and be a stepped-up version of the White Diamond.  We added three inches to the  White Diamond 's length, narrowed it a half an inch and added a touch of rocker to the nose and tail.  By doing that we have given this board the ability to handle bigger punchier surf than the White Diamond ,so we call it the Black Diamond. ​

FEATURES
