The JS Sub Xero is a super-groveler surfboard designed by Jason Stevenson for slow, small, knee-to-waist-high surf (0 to 4 feet)
Key Design & Features
Model Lineage: Combines elements of the JS Xero and the Psycho Nitro, acting as the smallest-wave board in the Xero family.
Outline & Rocker: Features a low-to-flat rocker with a slight nose flip, a wider outline with forward foam distribution for easy paddling, and a pulled-in swallow tail.
Bottom Contours: Rolled vee in the nose transitioning into a single-to-double concave, and vee out the tail for quick release.
Rails: Low, bladed, EasyRider-style rails that let you maintain high volume while keeping a sensitive, high-performance feel.
