About the Collaboration – Designer x Brand Alignment
KNOCK is a brand built on the energy of martial arts and the attitude of streetwear — a space where discipline meets rebellion. As a designer who’s long been inspired by street culture, urban symbolism, and bold personal expression, this collaboration felt instinctive.
When I was commissioned to design for KNOCK, I saw a rare alignment: a brand that celebrates both the inner warrior and outer style — exactly what I strive to capture in my work.
The result was “Astroknee” — a surreal visual that bridges the grounded intensity of Muaythai with the vast, dreamlike symbolism of space. It’s a fighter’s story told in texture and ink.
This design became one of KNOCK’s most iconic and best-selling pieces — not just because of how it looks, but because of what it represents.
From sketch to final impact.
A glimpse into the raw creative flow behind Astroknee — from early pencil lines to textured finish.
Early exploration of the fighter’s form.
The posture is rooted in the Muaythai technique. The helmet? A symbol of the untouchable — the dreamer in the chaos.
Clean lines. Focused energy.
Every contour and element was designed to communicate movement, pressure, and symbolic contrast.
Applied on premium apparel.
This design became one of Knockdown Wear’s top-selling graphics — worn by fighters and fans around the world.
Street presence.
The art lives beyond garments — showcased in urban poster ads as a visual anthem for rebel brands.
“Fight grounded. Dream unbound.”
More than a motto — a mindset behind every stroke of this design.
Behind the knockout.
