Borealis Koi Split 2027

The Ultimate Directional Surf Splitboard

Designed around a surf-inspired approach to backcountry riding, the Koi Split combines efficient touring with a natural, flowing descent.

Its directional shape is particularly effective in deep snow and tight terrain, while remaining composed when the route opens into steeper alpine faces.

On the descent, the Koi Split also provides powerful carving performance, allowing you to drive confidently through turns when the terrain becomes firm, steep or fast.

Touring Meets Snowsurfing

Built to make both the ascent and descent enjoyable, the Koi Split combines practical touring performance with a highly surfy ride.

Carving on the Descent

When the snow firms up, the Koi Split remains precise and powerful through the turn, allowing confident carving between deeper backcountry sections.
