Grennan Twin

A San Diego famous design, first invented by local legend, Jeff Grennan, quickly adopted by Frye and others. 

Growing up in San Diego, I've been privilege enough to meet and surf with Jeff.  I'm stoked to continue sharing the unique design. These are Grennan templates, the foils and layups are way different than your standard shelf fins. 

These were released recently by Jeff, bigger than the standard large side fins also known as "3's" These are larger and a proper twin sizing.
