Quad SUP Surfing Fins For Enhanced Speed and Control

The Strike4 Quad fins were designed to deliver speed and control. The upright template with increased stiffness generates speed and is ideally suited to boards with wider tails in smaller waves or for use in bigger waves when more fin area provides grip and security.

Best For:


Full Carbon Construction with LiteCore Technology

The full 24T carbon layup features our carbon-infused LiteCore technology enables us to control weight, strength, and flex precisely. For 2024 we reconfigured the layup – which uses unidirectional and woven carbon layers, increased the number of carbon layers in the base for increased strength and lateral stiffness and incorporated a 3k twill carbon finish to match the look of our surf paddles for cohesive branding. The result is a surf fin which is more responsive, lighter, higher performing and stronger. From only 125 grams per set (4.4 oz) these the lightest surf fins available.

Fin Case Like No Other

Included with each fin set is our premium surf fin case which has plenty of padded protection for multiple fin sets, tools, stickers, screws, leash string, fin keys etc. Ideal for travelling, organization and protection. The case has five (5) fin sleeves and a mesh pocket, durable construction and Velcro fastening.

New Branding & Artwork

The new SUP surfing fin sets feature our invigorated branding. The new design concepts will enable us to enhance product and brand image in the years ahead. We changed the color of the rear fins for easy identification and a striking look when installed.
