A performance-based board with more versatility and range in small surf and big surf. The initial idea came from Kelly Slater who envisioned a blunt nose performance shortboard with parallel rails and a unusual double barrel V bottom contour into a vee. The S Boss is a responsive performance shortboard with a tight turning radius that works in a huge range of surf.

Sizing wise Firewire recommend being cautious and choosing a size with a little more volume than you would typically ride.

I-Bolic Technology

  • Patent Pending technology built into the core blank construction creating preloaded structural flex together with structure strength and durability
  • Fibre Reinforced I-Beam down the centre with Parabolic Rail Springers from nose to tail
  • Three independent points for flex control and break resistance
  • I-Beam ensures firmness underfoot and unparalleled break strength
  • Two Parabolic Rail Springers enable flex and recoil during turns
  • I-Bolic Technology is an engineering feat that builds performance into the core of the surfboard, no external carbon layups or heavy laminations needed
  • A leap forward in surfboard manufacturing with an interplay of the favourite elements of LFT and Helium combined

Volcanic Technology

Volcanic Tech is made from Basalt Fibres extruded from volcanic rocks that are crushed, melted and extruded into woven fibres that make up the cloth layers that wrap around the board. The cloth features similar characteristics to carbon in regard to strength and weight however, being constructed from natural organic materials, it is a better degradable ECO alternative than traditional carbon fibre cloth. Basalt fibres have better strength characteristics than traditional glass fibres, and unlike most glass fibres is highly resistant to alkaline, acidic and salt corrosion. Basalt fibres also have more flex than traditional Carbon fibre, allowing the board to have more flex for a natural feel under foot.
