The De-Saphix-Fsi1 jacket by Diesel reinterprets biker codes with a streamlined racer attitude in a slim, cropped silhouette. The round collar extends into a long wraparound strap secured by a logo button and finished with a metal D detail, creating a distinct signature. Crafted from light-blue satin denim in a cotton-hemp blend, the fabric shimmers with ultra-fine metallic threads while laser treatments and a hand-sprayed finish produce delicate contrasts and a refined lived-in effect. A convex D-logo button set in transparent resin and an embossed leather back label add jewel-like accents, while considered tailoring ensures contemporary versatility.
