SlaterDesigns surfboard fin set * Size: Medium * Foam core * Carbon lay-up * Pixelated matte shark skin style * Endorfins branding * Colour: Black/White Kelly Slater combines the K2.1 and the K3 templates to create the ultimate all-round fin set. It can be used in any board and any condition, from small, groveler waves to pumping waves. Firewire’s new Endorfins are responsive and light that it floats! These fins are slightly larger than other quad rears, which allow for a tighter cluster. Kelly Slater uses them on his surfing boards. The fins have a matte, pixelated “shark skin”, which help to shed water while the board is moving down the line. It also features Kelly Slater’s trademark round graphic that has become synonymous for his fins.
