FCS Matt Biolos PC Carbon Medium Thruster Fins — stiff, explosive carbon thruster set co-designed with LOST Surfboards head shaper Matt Biolos for surfers chasing radical performance.

Biolos built this template for fast, committed surfing — a shape that prioritizes bottom-turn drive and rapid direction changes in punchy, high-performance conditions. PC Carbon construction layers carbon fiber over a Performance Core base, making these fins significantly stiffer and lighter than standard PC. That stiffness converts directly into explosive acceleration off the bottom and hair-trigger snap off the top.

• PC Carbon construction: carbon overlay over Performance Core for max stiffness-to-weight ratio
• Matt Biolos signature template: tuned for radical shortboard surfing with fast tail release
• Reduced drag: upright template generates speed in punchy, hollow conditions
• FCS II compatible: tool-free click-in system, no screws required
• Medium size: recommended for surfers 145–185 lbs
• Thruster (3-fin) set

At home in beach breaks and hollow reef waves where you want your board to react instantly. Pair with a LOST or high-performance shortboard to unlock the full benefit of the Biolos template.

Sizing: Medium suits surfers approximately 145–185 lbs. Size up if you're toward the heavier end or prefer added drive.

Care: Rinse with fresh water after each session. Inspect fin bases and plugs regularly for wear.
