Overview
TheSkindog Single Fin, available in 7" and the new 8" size, is designed to deliver a powerful yet fluid feel, perfect for harnessing speed and control in bigger surf. Paired with theSkindog Side Bytes, these fins create a 2 + 1 setup that enhances drive, stability, andmaneuverability. The side bytes add speed and control, allowing surfers to handle critical sections andmaintain stability through sweeping turns. Together, the setup offers a dynamic and versatile longboard experience, ideal for both traditional and progressive surfing styles.
Both the Skindog Single Fin and Side Bytes feature Performance Core (PC) construction with innovativeAirCore technology. This design incorporates a pressed polyurethane foam core that mimics the geometric foil of the fin, reducing the amount of fiberglass needed in the resin transfer moulding (RTM) process. The result is a significantly lighter fin with precise flex characteristics.AirCore technology allows for total manipulation of the flex, enhancing responsiveness and control, while maintaining durability and high performance across a variety of wave conditions.

A quick note about our photos!
We use a mix of official brand images and real-life shots from our warehouse to help you make an informed decision.
That said, what you see might differ slightly from what you receive — simply because we can't photograph every possible variation.
For example, a photo might show a 6'2 board with Futures fin boxes, while you've selected a 5'10 with FCS II. Don’t worry — you’ll get exactly what you ordered.
Sometimes, small details like the logo, its placement or overall colour tones can vary slightly depending on the production batch, camera, lighting, or even your screen settings.
These are always only minor differences, and in most cases, the photos are spot on - but we totally get that buying online can feel tricky. If you ever want more details, just drop us a message — we're happy to help!
