HONEYCOMB CONSTRUCTION
Honeycomb fins have a lightweight hexagonal core which reduces the weight and maintains the flex properties. These fins are engineered with a medium flex pattern, making them stiffer than Blackstix but more flexible than fiberglass. These fins have a Ride Number range of 4-7 and are great all around fins for any condition.
