Prada Back Triangle-Logo High-Collar Jacket – Black – Men’sYS8400911

Prada Back Triangle-Logo High-Collar Jacket – Black

The Prada jacket that carries more material and production specification than any other piece in the range. The shell is constructed from ECONYL® regenerated nylon — Prada’s proprietary sustainable nylon fabric produced through a depolymerization and repolymerization process that extracts and purifies nylon polymer from ocean plastic waste, fishing nets, and industrial nylon offcuts, then rebuilds it into a virgin-equivalent nylon yarn. Custom-woven to a high-density specification and treated with liquid ammonia to produce the shell’s defining surface character: hard, smooth, non-crease, and with a structured drape that reads as industrial rather than soft. The credential is the Prada inverted triangle hardware badge at the back collar — custom die-cast in full-steel chrome-plated construction, with precision-engraved Prada lettering and a cross-grain leather backing. Every seam is stitched on a JUKI industrial sewing machine with imported thread for stitch-line fineness and bond strength. The Oversize silhouette. The jacket that is — at every level of its construction — a deliberate specification decision.

Why You’ll Love It

• ECONYL® Regenerated Nylon – Ocean Plastic to Luxury Shell: The jacket shell constructed from ECONYL® — the regenerated nylon fiber developed by Aquafil and adopted by Prada as the primary material of its Re-Nylon program, the first luxury house to introduce regenerated nylon at scale across its product range. ECONYL® is produced through a two-stage chemical recycling process: depolymerization breaks recovered ocean plastic waste, discarded fishing nets, and industrial nylon offcuts down to the base nylon monomer (caprolactam); repolymerization rebuilds the monomer into a purified nylon polymer chain chemically identical to virgin nylon 6. The resulting ECONYL® yarn performs identically to virgin nylon in tensile strength, surface character, dyeability, and durability — while diverting ocean-bound plastic from marine ecosystems and eliminating the petroleum feedstock required to produce an equivalent volume of virgin nylon. The shell material that is Prada’s sustainability credential and its industrial-nylon aesthetic credential simultaneously: the fabric that reads as premium, structured, and industrial on the surface, and carries the material provenance of ocean plastic recovery at the fiber level.
• Liquid Ammonia Treatment – Hard Surface, Smooth Drape, Non-Crease: The ECONYL® shell subjected to a liquid ammonia finishing treatment — the process that produces the jacket’s defining surface character. Liquid ammonia treatment modifies the nylon fiber’s surface at the molecular level: the ammonia temporarily swells the fiber, reorganizes the polymer chain alignment, and, upon controlled evaporation, sets the fiber in a more ordered, smoother surface state. The result is a fabric that is simultaneously harder in hand-feel than untreated nylon, smoother in surface texture (the fiber irregularities that cause surface friction are reduced by the polymer realignment), and more resistant to creasing under compression (the improved polymer alignment gives the fabric a dimensional memory that resists fold-set formation). The liquid ammonia finish that produces the jacket’s “hard, smooth, structured” surface read — the industrial quality that makes it read as a high-specification material rather than a soft or conventional nylon shell.
• High-Density Custom Nylon Weave – Weather Resistance & Structural Body: The ECONYL® shell woven to a custom high-density specification — a tight, close weave that produces two functional properties absent from standard-density nylon fabrics. First, weather resistance: the high-density weave closes the gaps between individual yarn threads to a size that prevents liquid water penetration under standard rainfall conditions — a water-repellent performance derived from weave density rather than from a DWR (durable water repellent) coating that degrades with washing. Second, structural body: a high-density weave has more yarn per unit area than a standard weave, producing a fabric with greater stiffness and dimensional stability — the fabric body that allows the jacket to hold its Oversize silhouette without collapsing inward or losing its shoulder and chest structure during wear.
• Back Triangle-Logo Hardware – Full-Steel Chrome-Plated, Precision-Engraved, Cross-Grain Leather Backing: The Prada inverted triangle badge at the back collar — the house’s hardware credential in its most specified production form. Custom die-cast in full steel with chrome electroplating: the plating process that produces the mirror-surface finish and the lettering clarity that distinguish a full-steel chrome-plated badge from a zinc-alloy or resin badge with a surface metallic finish. The Prada lettering precision-engraved into the die-cast face: engraving rather than embossing or printing, so the letterform edges are defined by removed material rather than by applied surface — the edge definition that reads at close range as sharp, deep, and machine-precise. The cross-grain leather backing: the leather panel behind the steel badge that sits against the fabric and provides the badge’s attachment base, adds a material layer between the steel badge and the nylon shell, and reads as a bespoke hardware assembly rather than a standard badge-on-fabric attachment. Mirror finish. Lettering clarity. The badge that reads correctly from every viewing distance.
• JUKI Industrial Sewing Machine – Imported Thread, Stitch-Line Fineness & Bond Strength: Every seam on this jacket stitched on a JUKI industrial sewing machine with imported sewing thread — the production specification that determines stitch-line fineness, stitch-to-stitch consistency, and seam bond strength across the full garment. JUKI industrial machines operate at higher stitch-per-minute rates and more consistent stitch tension than standard production machines, producing seam lines with finer, more evenly spaced stitches and more consistent thread tension across the full seam length. On the ECONYL® high-density nylon shell, seam quality is a surface-visible quality indicator: the smooth, hard nylon surface makes stitch-line irregularity immediately visible as a deviation from the flat fabric plane. The JUKI machine’s stitch consistency produces seam lines that sit flush with the nylon surface rather than puckering or dragging the fabric — the seam quality that reads as precise manufacturing rather than production-line efficiency.
• Oversize Silhouette – Trend-Aligned Volume, Structured Hold: An Oversize cut with a generous chest, full shoulder width, and a body length that reads as a mid-length outerwear layer rather than a cropped jacket. On the high-density liquid-ammonia-treated ECONYL® shell, the Oversize silhouette is supported by the fabric’s structural body rather than relying on internal construction: the fabric holds the shoulder, chest, and sleeve volume without the internal padding or boning that a softer shell would require to maintain equivalent structure. The Oversize proportion that is the FW26 silhouette direction — the jacket cut that reads as directional rather than classic, and that positions this as the current-season Prada outerwear expression rather than a perennial format.
• High-Collar Zip – Full Neck Coverage, Industrial Aesthetic: A high stand collar with a full-length zip at the center-front placket — the collar construction that closes completely at the throat for full neck coverage and reads as industrial rather than tailored. The high collar that frames the back triangle badge at the collar base: the badge visible at the back neckline when the collar is zipped, positioned where the garment’s credential reads first from behind. The zip hardware in a finish consistent with the chrome badge — the hardware language unified from collar badge to zip pull.
• Utility Pockets – Clean Exterior, Functional Interior: External pockets on the front body — the functional addition that gives the jacket its utility register without interrupting the clean ECONYL® surface. The pocket placement and construction that reads as “simple and refined, highly fashionable” in the brief: the pocket that is present for function and reads as deliberate in placement rather than as a styling addition.
