K2 Instrument vs Sims UAP

How they compare

Both target all mountain and freeride terrain, while the K2 Instrument leans more powder. The K2 Instrument uses a directional shape while the Sims UAP is directional twin. The K2 Instrument has a hybrid (rocker/camber) profile (mix of camber and rocker zones for all-mountain versatility—grip, float, and play in one profile), while the Sims UAP uses camber (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise). Both are rated 7/10 flex (stiff).
