JUUN.J has unveiled a capsule collection with Alpinestars RSRV, the experimental arm of the Italian motorsport brand. The project brings together JUUN.J’s architectural approach to tailoring and the technical codes of motorsport gear, first revealed in January during the finale of JUUN.J’s Fall/Winter 2026 show at the Théâtre National de Chaillot in Paris.

Alpinestars has spent over six decades at the forefront of motorsports protection, and more recently has found itself embedded in fashion’s ongoing fascination with motocross and racing culture. Its RSRV line pushes that crossover further, translating protective construction and technical functionality into a more fashion-driven context.

The capsule comprises 17 styles, spanning nine menswear pieces, five womenswear pieces, and three accessories. At the centre are leather bombers and rider jackets that combine JUUN.J’s oversized silhouette with exaggerated padding and intricate leather patchwork. Denim and headwear extend the collaboration across a broader wardrobe. Rather than relying on logo treatments, the collection folds elements of motorcycle equipment into JUUN.J’s precise tailoring, reframing protective volumes and technical detailing through a luxury lens.

“This collaboration brings together JUUN.J’s reinterpretation of the classics with Alpinestars’ motorsports heritage to create something both futuristic and dynamic,” said JUUN.J Creative Director Jung Wook-jun. “By translating the speed and rebellious spirit of motorsports into JUUN.J’s structured approach to luxury, we hope to offer our global audience a new visual perspective.” The collection will be available at the JUUN.J Dosan flagship store, select JUUN.J locations at major department stores across Korea, and through SSF Shop.
