Product Description

The FCS II MR78 Twin PG L–XL Surfboard Fins in Dark Sunset are a modern take on Mark Richards’ iconic twin-fin design, tuned for speed, flow and drive. Based on the MR78 template, these fins deliver fast down-the-line speed with confident hold, making them ideal for surfers who want the freedom of a twin without the loose, skatey feel of smaller templates.

Built using Performance Glass (PG) construction, the MR78 Twins offer a solid, connected feel with a smooth, predictable flex pattern. This gives excellent control at higher speeds and plenty of drive through longer turns, especially in clean, open-face waves. Compared to lighter composite constructions, PG feels more planted and reliable, which suits the powerful nature of this twin template.

The L–XL size is designed for larger or more powerful surfers, or anyone riding bigger twins or fish boards who wants maximum speed with added control. Fully compatible with the FCS II tool-free system, these fins are easy to fit and remove, making them a great choice for modern twin-fin setups.
