K2 Afterblack Snowboard 2026

The K2 Afterblack Snowboard delivers progressive freestyle performance for riders who refuse to be confined to the park. Its medium flex pattern hits the sweet spot between buttery maneuverability and explosive rebound energy, while the true twin shape with blunted tip excels at presses and rail slides. Trusted by riders like Justin Phipps, this all-mountain freestyle machine transforms the entire mountain into a canvas. Perfect for intermediate to advanced riders seeking maximum style points.

Product Details

Rocker Type

Twin Combination Camber ProfileThe best of both worlds. By blending both traditional Camber and Rocker profiles, Combination Camber gives you all the benefits of both: the pop and precision of camber, and the float and predictability of rocker.

Flex

Flex Rating5 (1 Playful - 10 Precise)

Core

BAP CoreBamboo. Aspen. Paulownia. K2 has blended three species of renewable timber to assemble a core that’s strong, lightweight, and designed to enhance dampening without the addition of other materials.

Laminates

Carbon DarkWeb™A carbon fiber X-pattern that is strategically placed underfoot from edge-to-edge to speed up transitions, increase control, and increase underfoot strength.

Triaxial GlassA glass laminate with diagonal layers that adds torsional stiffness for increased stability and improved edge hold. The fibers three layers of fibers are woven at 45° , 45° , and 0° . This makes for a more responsive ride longitudinally and torsionally.

Base

Sintered 4000 BaseThe sintered 4000 base absorbs wax deep into the material for relentless glide and unrivaled durability.

Additional Features

Hybritech™ ConstructionBacked by years of rigorous testing, Hybritech is the lightest weight, most durable snowboard construction on the market. Removing excess sidewall material in the tip and tail and adding a 3D capped edge to increase the bond strength of the fiberglass and decrease the swing weight of the board is what makes Hybritech so revolutionary, helping K2 boards spin faster, maneuver easier, and last longer.
