Snowboards comparison — 2024-2025 season
Compare two models
How they compare
Both target all mountain terrain, while the Arbor Westmark leans more freestyle, while the K2 Instrument leans more freeride/powder. The Arbor Westmark uses a twin shape while the K2 Instrument is directional. The Arbor Westmark has a rocker profile (lifted contact points for easier turn initiation, float in soft snow, and a catch-free feel), while the K2 Instrument uses hybrid (rocker/camber) (mix of camber and rocker zones for all-mountain versatility—grip, float, and play in one profile). The K2 Instrument is slightly stiffer, though both sit in the medium range.
