The JS Industries Sub Xero Carbotune Surfboard 5'3 25.6L is JS's most performance-focused shortboard template built in Carbotune construction — carbon fiber reinforcement over an EPS blank for maximum stiffness-to-weight ratio. The result is a board that pops off the lip harder, responds faster, and feels more direct than a standard glass job. Designed for experienced surfers who want elite-level response and pop in solid surf.

• Construction: Carbotune — carbon fiber-reinforced laminate over EPS/epoxy blank; lighter and stiffer than HYFI for direct, explosive performance
• Template: Sub Xero — concave to double concave through the tail, pulled-in nose, narrow tail outline for maximum speed and precision in powerful waves
• Dimensions: 5'3 / 25.6L — compact, high-performance dims suited for lighter surfers or those who prefer to ride small for maximum responsiveness
• Fin System: FCS II — toolless, compatible with all FCS II fins in thruster or quad configuration
• Shaper: JS Industries
• Note: Consignment board — single unit available

Volume Note: 25.6L is a high-performance volume for this length. Best suited to surfers approximately 130–160 lbs who prefer a more pinned-down, responsive ride or those who regularly surf solid overhead-plus waves. Fins not included.

Care: Rinse with fresh water after each session. Store in a board bag away from direct sunlight. Repair any dings promptly — EPS/epoxy construction is particularly sensitive to water ingress through unrepaired dings.
