Monster of the Deep

If the permanent quest for deep powder and riding down steep lines at 200 mph are constantly on your mind, take a look at the new  Leviathan.
At first, the beast impresses with its exclusive long tip and monstrous swallow tail. It stays nonetheless very responsive thanks to its well-adapted effective edge and multiple sidecut radii which allow both to carve like hell at high speed like an mad Viking  and make short turns at low speed with maximum agility. But let's be clear about one thing: its true nature lies in deep powder, terrain on which it behaves like no other. Once you let go on the top of that steep face, only then will you witness what was put in place to create this mythical board: nose shape specifically adapted to effortless turns in powder, carefully-calculated width of the board for maximum float, optimised rocker-camber transitions, the tail's next-gen exclusive design which offers both float and mesmerising agility. A true eco-technological gem, designed by Borealis's boss and one of the most experienced american shapers in the industry.

Favourite Terrain







  • BLIZZARD CAMBER - This profile is ideal for deep powder float and solid grip on hard snow. Long front rocker starting from the front insert pack, mild camber down to the back insert pack and shorter rocker towards the tail for easier turns and switch landings.


  • BAMBOO TOPSHEET - This board is equipped with a 100% organic bamboo topsheet, making it dynamic, reducing chatter/vibrations and offering a more natural feel to the ride. It also reduced by 40% the quantity of plastic present in the board.​

  • ELEMENT CORE - Ultralight wood core made from a blend of special woods boosted with basalt rods. Thinner tip and tail for reduced swing weight. Dynamic, snappy and durable.

  • ZERO VOC RESIN - This board is assembled using Zero VOC Resin. It is a long-lasting and high-performance alternative to classic epoxy resins, with no harmful vapours.

  • SINTERED ELECTRA 4000 GRAPHITE BASE - This ultra-premium high-molecular density base is our  ultra-premium option. Reach mind-blowing speeds on any terrain and snow temperature. High impact-resilience and great wax-absorption. 

  • TRIAXIAL FIBREGLASS - This composite is weaved in 3 different angles, bringing precision, reactivity and stability to the board. High longitudinal and torsional stiffness.

  • BASALTECH - Organic biaxial basalt fiber made from crushed volcanic lava (no chemical process).

  • 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.​

  • FLAX PADS - 100% natural flax pads placed on the wood core, under the bindings. The result: a more comfortable ride, less vibrations and fatigue and a longer-lasting..Thank you Mother Nature.

  • NEXT-GEN SWALLOW TAIL - Great maneuverability and stability in powder, optimal float, reduced swing-weight.

“The shape really is a thing of beauty and the way it floats and connects with the terrain is like very few boards I’ve ridden before”

- Rob McCreath - Whitelines

Ce shape pure poudreuse avec gros soutien spatule est étonnamment facile à piloter au centre. Le talon joueur toujours prêt à l'action offre de la diversité.
