JS Surfboard 5'7 SUB XERO CARBOTUNE | 32L 5ft7

The Sub Xero is a high-performance small-wave board, blending the Xero and Psycho Nitro for speed and control in weak surf. It features a flat rocker, full outline, wider tail, and refined rails for quick turns and easy drive. A vee-to-concave bottom design maintains speed with minimal effort. Built for knee-high waves, it shines when waves are slow-making it the perfect "groveler." Size: 4-6 inches (10-15 cm) shorter than your regular Xero. CarboTune Technology: Carbon optimizes the weight-to-stiffness ratio, delivering fast, efficient response. Lightweight, precisely layered carbon ensures immediate energy transfer, ideal flex, and optimized overall weight - similar to the PU boards used by the pro team.
