JS Industries Sub Xero HYFI 3.0 – The Fastest Board for Slow Waves - Built for Super Groveling | Designed to Dominate Knee-High Peaks
The Sub Xero HYFI 3.0 is JS Industries’ most advanced small-wave weapon, engineered to bring maximum speed, lift, and responsiveness to otherwise forgettable surf. Blending DNA from the Xero and the legendary Psycho Nitro, this board is tuned to make waist-high mush feel like the skate park of your dreams.
Designed with low rocker, a wide tail block, and refined nose template, the Sub Xero generates unmatched speed while offering tight turning arcs with minimal effort. For surfers chasing summer grovel sessions, knee-high point breaks, or even junky beach break days, the Sub Xero makes the most of every bump on the wave face. Whether you’re a CT-level shredder like Julian Wilson or a weekend ripper looking to maximize fun, this is the fastest board for slow waves.
Concave: Slight vee in nose → single concave under front foot → double concave between fins → slight vee out of the swallow tail. Designed for rail-to-rail control, fast lift, and critical tail release.
Rail Type: Low, forgiving rails maintain responsiveness without compromising volume and paddling power.
Construction: HYFI 3.0 – 30% lighter and 20% stronger than standard PU. Lightweight flex with spring-loaded return and durability for daily abuse.
Rocker: Low-to-flat entry and exit rocker = instant speed generation + paddle ease in gutless surf.
Outline & Deck: Flatter deck + full volume = super buoyant planing with quick rail engagement via lower rails.
Fin Setup: Stock 5-fin setup (Thruster or Quad). Futures or FCS II compatible.
Quad for down-the-line speed | Thruster for added control and vertical punch.
Glassing Specs: 5'2"–5'9": 4 oz deck / 4 oz bottom, 5'10"–6'4": 4x3 oz deck / 4 oz bottom, 6'6"+: 4x4 oz deck / 4 oz bottom, All with Hybrid Fibre tail reinforcements.
