Description

The same KS1 as the standard version — an upright template with strong pivot, drawn by the 11× world champion. The difference is the finish: a collaboration with Outerknown, Slater's own clothing brand, hence the camouflage.

An upright outline means turning around a point rather than along an arc: short, sharp direction changes in the pocket. It's the opposite of the raked KSR.

Construction uses carbon inlays that let the core be 90% air. The fins carry load and literally float if one gets away from you.

Single tab variants are compatible with the Futures fin system.

Who it isn't for. Long drawn-out arcs and drive down the line want a raked template. And check your boxes: FCS II needs its own variant.
