ONYX. JKT

JŪN’s First Track Jacket.

Crafted in black and navy twill, JŪN’s ONYX. jacket redefines the classic track silhouette through precision and detail. The twill weave provides both durability and depth, while the tailored cut and subtle contrast accents give it a sharp, elevated finish.

The ONYX. — named after the deep, enduring stone — represents strength, refinement, and timeless design. It introduces JŪN’s newest detail: French cuffs reimagined for a track jacket sleeve, merging heritage tailoring with modern sportswear.

Designer’s Note:
“ONYX is about pushing boundaries in subtle ways. Using twill gives the jacket structure and weight, while the French cuff sleeve adds a refined twist you’d never expect on a track jacket. It’s sleek, versatile, and a signal of how we’re shaping JŪN’s future designs.”
