K2 Isolator Splitboard—a stiff, directional tool for powerful backcountry exploration
What Our Gearhead® Experts Are Saying:
"The Isolator Split is the board I trust when conditions get sketchy. The stiff flex, camber profile, and swallowtail combine for precision, float, and control whether I’m threading tight couloirs or charging open alpine faces."
Who It’s For
Confident backcountry riders chasing steep, technical lines
The Isolator is made for intermediate to expert riders who want a split that rides like a solid board. Its stiff flex and camber-heavy profile thrive in challenging terrain where precision and snap matter most.
What It’s For
Big mountain powder lines and technical backcountry tours
The Isolator’s oversized nose and swallowtail sink and float through deep snow, while its directional camber profile locks in edge hold for stability on sketchy approaches and steep descents. Paired with Karakoram UltraClips, it delivers a locked-in, responsive ride.
Why We Like It
Solid feel, split versatility
K2 borrowed proven design cues from the Excavator and re-engineered them for splitboarding. The result? A board that climbs efficiently yet charges downhill like a freeride deck. Its Paulownia Tour-Lite core keeps the weight manageable for long tours, while ICG 10 Carbon Glass stiffens up response without adding excess weight.
