Zack Flores Compares Poly, EPS, and XTR Foam in Surfboard Testing

Zack Flores, a skilled surfboard shaper, has initiated a test to identify the best foam material for surfboard construction. He is comparing polyurethane, expanded polystyrene, and extruded polystyrene foams in a series of real-world tests.

The testing process involves shaping and glassing boards made from each foam type, followed by rigorous evaluations of their durability, strength, weight, and performance in the water. Flores aims to provide insights into how each material holds up under typical surfing conditions.

This exploration reflects the evolution of surfboard materials, moving from traditional woods to modern foams, highlighting the advancements in surfboard design.
