The K4 3SW Freewave fin is designed to provide maximum control and power for freestyle-wave windsurfing, from waves to freestyle and bump ‘n’ jump. This plastic molded fin is lightweight, stiff, durable, and fast, thanks to its Super Stiff composite material. The 3SW’s unique design allows it to handle the most challenging conditions easily, making it perfect for onshore slogging or fully powered blasting.

It has been tested extensively in a wide range of conditions and has repeatedly proven to be an incredibly reliable choice in hard-core wave sailing situations. The fin’s stiff construction ensures it won’t flex under pressure, allowing maximum speed and control through turns.
