The ultimate choice for deep powder and versatile carving. Inspired by Hokkaido's legendary snowfalls, the Koi Split is a directional, surf-inspired splitboard designed for deep powder adventures and confident edge-hold on hard or icy snow. Its Japanese heritage is reflected in its name and minimalist graphics, making it an iconic model in the Borealis lineup. Launched in 2015, the Koi Split remains our most balanced directional powder shape. Key features for peak performance include an elongated, rockered tip, tapered shape, and agile fish tail that provide outstanding lift and nimble handling in deep snow. A wide sidecut and innovative Sidewaves ensure precise, powerful turns on firm terrain. The high-performance DS4001 sintered base is exceptionally fast, absorbs wax efficiently, and is built to last. The Koi Split is a versatile and controlled ride, perfect for weaving through forests or charging open faces. Experience a new frontier in riding with the next-generation Borealis Koi Splitboard.
