Arbor Relapse vs K2 Instrument

How they compare

Both target all mountain terrain, while the Arbor Relapse leans more freestyle, while the K2 Instrument leans more freeride/powder. The Arbor Relapse uses a twin shape while the K2 Instrument is directional. The Arbor Relapse has a camber profile (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise), 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.
