[PRE-ORDER] Borealis Koi Splitboard

Borealis Koi Split 2027 | The Ultimate Directional Surf-Splitboard

Inspired by the legendary snowfalls of Hokkaido, the Koi Split 2027 remains the most iconic directional powder shape in the Borealis lineup. This surf-inspired splitboard is engineered for deep backcountry adventures, offering a perfect balance between technical forest navigation and high-speed alpine charging. For 2027, it features a stunning aesthetic update with a wood-texture finish that highlights its organic soul.

Tree-Run Agility & Alpine Power

The Koi Split is the ultimate weapon for tight forest sessions, where its short fish tail and tapered shape allow for lightning-fast, reactive pivoting between trees. However, thanks to its large sidecut radius, it is equally formidable on open alpine faces above the tree line. This versatility ensures a stable, "surfy" feel whether you are weaving through technical glades or pinning it down wide-open powder bowls.

Edge Synergy Technology: Total Control

Featuring an extra-long nose with a highly progressive rocker, the Koi surmounts deep snow with effortless ease. When conditions get firm, our Edge Synergy Technology—which includes our innovative Sidewaves—provides surgical edge hold on icy ridges. This integrated system harmonises the sidecut with strategic contact points, ensuring you remain confident and stable on the most challenging, wind-blown terrain.

DNA Bioplastic & Ultra Light Forest Core

The 2027 edition is equipped with our new DNA Bioplastic Topsheet (textured) and our premium Ultra Light Forest Core. This makes the board incredibly solid, scratch-resistant, and remarkably lightweight for the skin track. This heavy-duty construction is why we confidently back the Koi Split with our 4-year warranty. Crafted with a race-grade DS4001 sintered base and Zero-VOC resin, it is a masterpiece of eco-engineering close to perfection.
