In short

The Borealis Koi Split is the answer to swift turns in powdery forests and epic freeride lines. This board is a tribute to the Japanese backcountry. It is simple, elegant and floats like nothing you’ve tried before. Take a deep breath, find your inner silence and let go.

In detail

PROFILE

  • Powder Camber
    Huge front rocker that will keep you above the deepest snow, flat zone for more stability, positive camber down to the tail for powerful turns.

CORE

  • UL Forest Core
    Ultralight wood core made from sustainable woods (poplar, paulownia) reinforced with bamboo rods. Thinner tip and tail for reduced swing weight. Dynamic, snappy and durable.
  • Carbon Power Beams
    Our carefully-studied carbon reinforcement matrix are designed for each board's needs. Wether the aim is to boost pop, stability or precision, these beams are the central nervous system of your ride, making it more dynamic and swift.

  • Powder Paw
    Long strips of intermeshed Kevlar© and carbon placed on strategic zones of the core reducing vibrations and making the ride smoother, just as a lynx's paw pads.

  • Tail Shield
    The shield has your back: it will help protect your board against rocks, hidden roots or any other obstacle.

TOPSHEET

  • DNA Bioplastic Topsheet
    Plant-based (50%) organic topsheet with improved resistance to impacts and low snow adherence properties, allowing to slide through powder with less friction.

  • Permafrost Technology
    Through an exclusive process, the fibers of the bamboo topsheet are infused with Greenpoxy© Eco-Resin, making it impact-resistant and long-lasting.

  • Greenpoxy Eco-Resin
    This board is assembled using the Greenpoxy Eco-Resin, made from 55+% of recycled biomass such as recycled vegetable oils and sawdust. This very low-VOC (volatile organic compound) bio-resin is a long-lasting and high-performance alternative to classic epoxy resins.

  • Triax Glass x2
    This composite is weaved in 3 different angles, bringing precision, reactivity and stability to the board. High longitudinal and torsional stifness.

BASE

  • 4001 Sintered Base
    This premium high-molecular density base is a high-end option. Super fast on any terrain and snow temperature. High impact-resilience and great wax-absorption.

SIDEWALL

  • Liquid Walls
    A sidewall that’s poured directly into the core during the production process. Applied in a liquid shape, after solidifying this wall is more or less bulletproof.

  • Sidewaves
    Extra contact points added to the sidecut offer more security and amazing grip on hard snow and ice. Very similar to Magnetraction.
