Paying homage to Hokkaido’s legendary snowfalls, the Koi Split is a directional, surf-inspired splitboard designed for deep powder adventures and confident carving on hard snow. Adorned with simple yet sophisticated colours, this board stands out as one of the most iconic models in the Borealis range—its Japanese heritage is evident in its name, minimalist graphics, and exceptional riding performance. Launched in 2015 in its snowboard version as one of our founding models, the Koi Split remains the most balanced directional powder shape in our collection. The elongated, rockered tip provides outstanding lift in deep snow, while the wide sidecut and innovative Sidewaves ensure precise, powerful turns on firm terrain. The agile fish tail allows for quick, responsive manoeuvres in the deepest conditions, making this board a true dream in powder. Whether you’re weaving through snow-laden forests or unleashing speed on open faces, the Koi Split delivers versatility and control. On hard snow, it carves deep, mesmerising trenches, ready to push your riding to new frontiers with its next-generation design.
 
Effortless Float
The long rockered tip, tapered shape, and short fish-like tail allow the Koi Split to glide effortlessly in powder and turn on a pin head.
