The Award-Winning All-Mountain Powder Snowboard
Inspired by the deep snow of Hokkaido, the Koi is designed to make powder riding feel natural while retaining enough precision for fast groomer laps.
Its unusual combination of a long nose, progressive rocker and compact tail gives it a distinctive surf-like character without turning it into a one-condition specialist.
The Koi also carves remarkably well for a powder-oriented shape, offering a smooth, powerful transition from edge to edge when you return to firm snow.
Six ride types, each scored from 1 to 10. The further the shape reaches toward a corner, the better the board performs there.
Surfy, fast and precise. Inspired by the deep snow of Hokkaido, the Koi makes powder riding feel natural, then carves remarkably well when you return to firm snow.
The long, buoyant nose and progressive rocker keep the Koi naturally high in deep snow, so you focus on your line rather than fighting for float.
The compact fishtail and tapered shape make the Koi surprisingly agile through trees and technical powder terrain.
The directional platform stays precise on firm snow, with a smooth, powerful transition from edge to edge.
Sidewaves, Liquid Sidewalls and the DS4001 sintered base combine durability, grip and speed.
Tighter at the ends, so the board turns easily at low speed. Larger in the centre, which takes over as you pick up speed, for stability in long, fast carves.
At each foot, a very subtle bump on both edges, set just ahead of the inserts and rising only 0.5 mm above the sidecut curve. It gives more bite on very hard snow and ice.
The sidecut curve meets the opposite curve of the nose and tail through a long, gradual transition. That gives more edge length gripping than on most snowboards.
