Choose your Mint or Lemon in one of our two full sandwich technologies!

Our FSP boards (for Full Sandwich PVC) feature the strongest technology currently available on the market. This no-compromise construction is a must to ensure durability capable of withstanding the extreme, intense, and repetitive mechanical stresses of wing foiling, especially for the most dedicated riders.

The FSP constructions available for the Mint and Lemon are:

FSP 2X construction with an outer biaxial fiberglass laminate.
FSP Pro construction with an outer carbon fiber laminate.

Which one should you choose? We guide you in this article!

What is a “full” sandwich construction?

A board built with full sandwich technology is wrapped around its entire foam core with a triple-layer structure, like a sandwich: Fiber layer / Core material / Fiber layer

The presence of this core material across the entire board, combined with the surrounding fiber layers, gives our boards exceptional mechanical performance. In particular, the sandwich construction on the rails forms a structural frame that works under load when the board flexes.

These boards offer absolute strength, with a core material that maintains spacing between the outer fiber layers and those surrounding the foam blank. The result is superior liveliness and unmatched durability, especially thanks to improved flex tolerance.

In addition, this type of board is highly resistant to heel dents. And even when dents occur, they have no structural impact on mechanical strength.

Good to know: Full sandwich boards are a premium technology and far from being the market standard. Many constructions only feature partial sandwich layers on the deck, or no sandwich at all. Ask for complete and detailed construction infographics.

What is the core material in an FSP 2X / FSP Pro board?

The core material in these constructions is a 3mm high-density PVC foam on our PVC-based boards. Its strengths are density, lightness, and waterproof properties.

A full PVC sandwich forms a rigid shell across the entire board, increasing stiffness, responsiveness, and comfort underfoot. This PVC shell is hydrophobic and protects the board from water ingress, for example if the outer fiber is damaged on rocks.

What is the difference between FSP 2X and FSP Pro?

The Full PVC Sandwich principle is applied in exactly the same way in both technologies, giving them nearly identical flex resistance, since the PVC frame plays the key structural role.

Where they differ is in the outer sandwich layer:

Two layers of fiberglass in the FSP 2X construction (including one biaxial layer).
One layer of carbon fiber in the FSP Pro construction, as shown in our detailed infographics.

Fiberglass or Carbon?

Using fiberglass or carbon enhances different qualities of your full sandwich board.

Weight

Because carbon is significantly stronger in tension than fiberglass, only one carbon layer is needed instead of two fiberglass layers, resulting in lower weight.

Weight is naturally critical when seeking performance, especially when talking about an object designed to fly. Performance matters in technical maneuvers, of course, but even simply taking off in ultra-light conditions is performance. So every percentage gained makes life easier on the water and improves sensations.

Responsiveness

An FSP Pro board delivers a more dynamic feel than an FSP 2X board. It is lighter, of course, but also offers greater dynamism thanks to increased stiffness.

This stiffness improves direct energy transmission between rider and board: each input is more precise, each impulse better returned. Your actions feel sharper. A clear advantage in committed maneuvers: accelerations, bouncing off water, powered turns, or stronger conditions.

Forgiveness

Fiberglass works more under load than carbon, whose mechanical resistance is higher. While carbon barely moves, fiberglass retains some memory of the load, translating into a smoother, more comfortable feel on the water.

For example, fiberglass Wood Flex constructions are recommended in twintip kitesurfing to protect your knees. In wing foiling, where joints are less stressed, fiberglass still provides a softer, more forgiving feel compared to a full carbon board.

Impact Resistance

This softer characteristic of fiberglass also provides better resistance to everyday impacts (a knee hit, contact with a rock, etc.).

Although carbon is globally much stronger and distributes energy better, especially in jumps, it is less tolerant in the case of direct, localized impacts.

To simplify: On an FSP 2X construction, a heavy impact will more likely create a dent before breaking. As a result, an FSP 2X board is more tolerant to everyday knocks (car trunk, stairs at the spot, etc.).

Why offer Mint and Lemon in two technologies?

The Mint and Lemon are boards that ideally bridge the gap between your first wing foil board and the most radical boards in the range.

The choice of construction allows you to position the cursor between accessibility and radical performance:

Choose generous volume with FSP 2X construction for smooth progression without skipping steps, ideal for steady improvement.
Choose lower volumes with FSP Pro construction for lighter weight, greater dynamism, and high-performance riding.

Conclusion

By choosing a full PVC sandwich board, whether FSP 2X or FSP Pro, you are choosing the most durable technology with the highest possible mechanical resistance.

This technology is also easy to repair after impact, as the hydrophobic PVC shell allows new fiber layers to adhere perfectly.

Between FSP 2X and FSP Pro, choose according to your expectations:

If accessibility and comfort are your priorities, FSP 2X offers all the guarantees you need
If you want the lightest, most dynamic board to boost sensations and performance, choose FSP Pro.
