What makes a surfboard feel lively, fast and connected under your feet?
Lost Surfboards’ BLACKSHEEP construction brings together a lightweight EPS core, carbon reinforcement and epoxy construction to create a board built for responsive, high-performance surfing. In this first part, we’ll break down what the technology is, how its carbon layout works, and what to keep in mind when caring for a BLACKSHEEP board.
What is BLACKSHEEP?
BLACKSHEEP is a Lost Surfboards construction designed to balance low weight, responsiveness and durability.
Its core is made from lightweight 1.5 lb EPS foam, reinforced with Triax-NCF carbon fiber and multiple layers of fiberglass. The carbon is applied to the deck, while the combination of materials helps the board feel lively underfoot and gives it a smooth, controlled flex.
Carbon laid out for drive and control
The carbon fibers are arranged on three axes: +30°, −30° and 0°. This layout is designed to spread energy evenly from rail to rail, helping deliver drive, control and a connected feeling through turns.
Unlike traditional woven carbon, the Triax-NCF design keeps the fibers flatter. According to the construction details, this reduces weak points and adds reinforcement without adding weight. The result is a lightweight, responsive board built to handle the demands of performance surfing.
How does it feel in the water?
BLACKSHEEP boards are designed to generate speed, accelerate through turns and maintain control across a wide range of wave conditions. Compared with traditional PU surfboards, the construction is described as offering improved strength for its weight and retaining its flex over time.
That makes BLACKSHEEP an option for intermediate to advanced surfers looking for a fast, responsive feel in everyday waves, with a construction designed for durability as well as performance.
A quick note on care
Carbon fiber absorbs heat, so BLACKSHEEP boards need protection from high temperatures.
Avoid leaving your board in a hot car or in direct sunlight, and use a reflective day bag to help keep it safe. With proper care, it can stay light, lively and ready for many more sessions.

Mod Quad by Matt Biolos
Made for playful everyday surf. Matt Biolos adapted Lost’s Hawaiian hybrid quads for Shane Beschen and Pops Ho to suit the smaller, softer waves of California and the East Coast.
Speed, lift and hold. A fast entry, low rocker and drivey tail rocker set up speed; the deep single concave adds lift. The curved rail line helps it turn, while the tail Vee acts like a rear fin, guiding and holding through turns. A wide, skatey outline, forgiving nose and set-back wide point flow into a moderate swallow tail, adding grip and pivot while retaining width for small-wave speed.
PISCES by Matt Biolos
Classic fish, modern feel. The Pisces sharpens the traditional fish for modern surf. Its pulled-in nose and extra front rocker help it handle steeper takeoffs, while a flatter midsection keeps it fast and lively down the line.
Lift, drive and multiple setups. Deeper center concaves generate lift and drive; a curved rail under the back foot brings control through turns. The subtle wing before the swallow tail adds release and pivot, while the contoured deck mirrors the bottom shaping for a balanced, responsive feel. Its five-fin setup lets you ride it as a thruster, quad, twin or hybrid to suit the conditions and your preferred approach.
Puddle Jumper by Matt Biolos
Made for small, soft surf. Matt Biolos designed the Puddle Jumper with the Mayhem crew to bring high-performance fun to less-than-perfect days. Its short, stubby outline, wide nose and generous volume under the chest help it paddle easily and catch waves early.
Speed with a loose, lively tail. Low entry rocker helps it fly through flat sections. A concave bottom flows into a tail Vee for speed, looseness and release, while the narrower tail keeps it snappy and drivey when the wave steepens. This small-wave board is made to be surfed, not just cruised.
RNF ’96 by Matt Biolos
Born from the original fish. Matt Biolos developed the first Lost fish for Chris Ward and Cory Lopez ahead of the 1997 surf film. With more than 25 years of shaping experience behind it, the RNF ’96 refines that original idea as a performance fish, built for more than small-wave speed.
Speed, drive and twin-fin freedom. Its single-to-double concave and accelerating vee combine speed and drive with smooth rail-to-rail transitions. Refined thickness, deck, rails and tail foil create a more balanced, predictable feel while preserving the original’s character. Paired with the Mark Richards twin-fin template and a small center stabilizer, it brings drive and speed with the freedom and maneuverability of a twin-fin setup.
RNF ’96 King Fish by Matt Biolos
RNF ’96 DNA, stretched for more glide. The King Fish extends and streamlines the original fish into a Mid-Length Mayhem, carrying over its proven design details in a longer outline.
Easy paddle. Long glide. Real turns. Low entry rocker helps with paddling and wave-catching. A flat deck and full, soft rails add float and stability, while keeping the board relatively thin and forgiving underfoot. A balanced outline, with modest, matched nose and tail widths, preserves curve for turning. Its shortboard-like tail and shallow swallow keep the ride from feeling too fishy. Underneath, the bottom moves from flat up front to a single concave, then into double-concave Vee that deepens through the tail for acceleration.
SUB DRIVER 3.0 by Matt Biolos
Small-wave performance, proven over years. The Sub Driver has been a staple in Lost’s amateur, WQS and Challenger Series quivers, as well as a performance shortboard for average surf. The swallow-tail 3.0 is the first release of an updated design refined over three to four years of rider feedback.
Fast lines, precise turns. Low tail rocker and a curvy rail line work with a deep single concave through the center, then double concave and a distinctive Vee behind the rear fin to create speed and drive. A set-back wide point forms a hip that sweeps into a moderately wide swallow, keeping the outline performance-oriented for turning.
Video Review: Analyzing Blacksheep Carbon Response
To truly understand how the carbon and flex behave on the wave, a real water test is key. In this video, our surfboard specialist Iker Treviño (@fl0wm4st3r) reviews the performance of Blacksheep technology using the Lost Rad Ripper surfboard as our test board.
Even though this exact shape is currently sold out, this review gives you a clear look at what you’ll feel on any of the Lost Blacksheep boards we have in stock.

Frequently Asked Questions
How does Blacksheep technology actually feel under your feet on a wave?
You’ll feel the difference immediately. Thanks to the lightweight EPS core and carbon layup, the board delivers instant acceleration off the drop and a lively “pop” underfoot. It makes generating speed effortless and helps you connect turns with much more flow in everyday conditions.
Is this construction fragile, or can it handle daily wear and tear?
It’s surprisingly tough. Even though the board feels remarkably light in your hands, the multi-directional Triax-NCF carbon layer combined with fiberglass creates a high-impact shell designed to withstand heavy sessions without sacrificing performance.
Is it worth choosing over a classic Polyurethane (PU) surfboard?
Absolutely, if speed and longevity are your main goals. While standard PU boards gradually lose their pop and flex over time, Blacksheep construction holds its lively, springy feel through countless sessions.
Why does a carbon board require special heat protection?
Carbon fiber naturally absorbs and holds heat much faster than a standard white surfboard. To help prevent the internal EPS core from expanding, avoid leaving it inside hot cars or in direct sunlight and always store it in a heat-reflective day bag.
Do I need to be a pro to ride a Lost Blacksheep board?
It’s designed mainly for intermediate to advanced surfers. If you already know how to generate your own speed and want a board that reacts instantly when you set an edge, you’ll get the most out of it right away.
