XTR surfboards are built with XTR 10 foam core technology, using 100% waterproof, extruded closed-cell foam that balances strength, flexibility, and durability. Unlike other epoxy boards, XTR boards eliminate the typical "chatter" and "overly buoyant" feel. Instead, they offer a "True to Poly" feel—smooth, stable, and responsive, even in choppy conditions.

The closed-cell foam structure ensures no water absorption in case of a ding, maintaining durability and performance over time. With the perfect balance of flexibility and stiffness, XTR boards keep their shape without becoming too flimsy or too stiff.

When ordering a custom XTR surfboard, selecting the right construction and flex pattern is essential for optimal performance. Each construction option falls within a specific flex value range, allowing you to tailor the board to your weight, riding style, and wave conditions.

XTR offers 4 different construction options:

• Parallel Carbon
• Carbon Lite
• Single Lite
• Wood Stringer

Parallel Carbon

• Torsional flex, most amount of spring, pop and response.
• Flex Value Range: 6-8
• Good construction option for groveler and hybrid models for head high and under wave conditions  
• Offers torsional flex for the most spring, pop, and response. Ideal for surfers looking for a lively, responsive board with maximum performance in a variety of wave conditions.

The precise carbon filament layup of your weight connects parallel to your stance directly to the fin boxes, creating instant drive, speed, and responsiveness. XTReme loading of pressure and release of spring resulting in equal amounts of pop and response, the most of any construction we offer.  Comes standard with carbon tail patches.

Carbon Lite

• Linear flex, mimics wood stringer with a feeling of added spring, pop and response.
• Flex Value Range: 5-6
• Good construction option for shortboards in shoulder-high to overhead wave conditions 
• Provides an increase in spring and response when compared to a wood stringer. A great choice for surfers who want lightning-fast response yet maintaining a balanced ride with added flexibility and pop.

Using a lite-weight carbon fiber placed directly on our XTR foam core from nose to tail on top and bottom provides liveliness, spring, and pop while still maintaining a traditional stiffness and rigidity of a center stringer-style flex. The carbon fiber's high strength-to-weight ratio allows for a thinner and lighter stringer, which can reduce the board's overall weight and increase its maneuverability and performance. Comes standard with carbon tail patches.

Single Lite

• Linear flex, highly versatile, good intro to stringerless construction.
• Flex Value Range: 4-5
• This option is highly versatile and offers a smooth and consistent flex pattern that works well across different weight ranges, surf styles and wave conditions.

Incorporated into the board's design, 8 carbon filaments in a diamond-cut carbon strip deck inlay integrated with carbon tail patches are applied to our XTR foam core provides forgiveness, support, and durability while the full carbon strip bottom maintains the board's rocker line giving a lively and responsive flex still true to the integrity of a standard wood stringer feeling. Comes standard with carbon tail patches.

Wood Stringer

• Linear flex, stiffest of all constructions, and closest to PU feel.
• Flex Value Range: 2
• The stiffest of all constructions, providing the most PU-like feel. Ideal for surfers who prefer a traditional, stable ride with less response and more control, especially for bigger waves.

XTR Wood Stringer option gives you all the benefits of our XTR 10 foam core and industry-leading epoxy resin. Our standard wood construction will provide you with the added liveliness and durability that XTR is known for but still keeping the traditional feel of a wood stringer flex.Linear flex, highly versatile, good intro to stringerless construction.

Flex refers to a surfboard’s ability to adapt and respond to the shape of the wave and the surfer’s movements in real-time. The ideal flex pattern depends on factors such as surfer weight, riding style, and the wave conditions you surf in.

To measure flex, place a static surfboard under the weight of a surfer. Lighter surfers experience more flex, while heavier surfers need a stiffer board for optimal performance.

• Lighter surfers (under 150 lbs) generally use boards with higher flex (7-10).
• Heavier surfers (200 lbs or more) typically prefer boards with lower flex (1-4).

• 1 = Most Stiff (closest to PU feel)
• 10 = Most Flexible (maximum flex)
