3M M1343 Sweatshirt - Black Diagonal Fleece Knit Spray Treatment Hood Unisex Made in Italy

The Surface Is the Statement.

The M1343 sweatshirt from LA HAINE INSIDE US begins where the M1344 ends — and then goes further. The same dual-fabric architecture: a 100% cotton diagonal fleece body intersected by Fineness 3 wool-blend knit inserts. But here, the knit panels have been treated with a spray finish that transforms their surface from textile to something closer to lacquer — dark, iridescent, and entirely unrepeatable. The spray catches light differently from every angle. The matte fleece does not. That contrast is the design. Unisex. Made in Italy.

Why This Sweatshirt Is Different

• Spray-Treated Knit Panels: The Fineness 3 knit inserts have been treated with a spray finish that creates a dark, lacquered, iridescent surface — wet-look in quality, textile in origin. No two pieces will catch the light in exactly the same way.
• Matte vs. Lacquer Contrast: The untreated diagonal fleece body remains matte and soft, creating a deliberate material contrast with the spray-finished knit panels that defines the garment’s visual identity.
• Dual-Fabric Construction: 100% cotton diagonal fleece body with 80% polyester, 20% wool Fineness 3 knit inserts — two distinct fabrics, one architectural garment.
• Spray-Treated Back Panel: The full back knit panel also carries the spray treatment, ensuring the garment is as striking from behind as it is from the front.
• Diagonal Fleece Body: Cut on the bias for directional texture and visual movement — the diagonal weave adds structural interest to the matte sections of the garment.
• Oversized Hood: Deep, structured, and dramatically proportioned — the hood adds volume and shadow to the silhouette when worn up.
• Comfort Fit: Generous, relaxed proportions designed to work across genders — the unisex cut sits comfortably on both male and female frames.
• Italian Craftsmanship: Designed and made in Italy, where surface treatment, mixed-material construction, and material precision are non-negotiable.

Unisex Size Chart

Comfort/unisex fit. Women typically size down one size for a relaxed silhouette, or wear true to size for an oversized look.

The Moment You Put It On

The fleece settles against the body with familiar weight. Then the light shifts — and the spray-treated panels catch it. Not a reflection, not a sheen: something between the two. Dark, iridescent, alive. The matte fleece recedes. The lacquered knit advances. The contrast between them is not subtle — it is the point.

Pull the hood up and the silhouette becomes something else entirely: architectural, protective, and entirely your own. This is a sweatshirt that changes with the light. No two wearings look exactly the same.

The Art of Spray Treatment

The spray treatment applied to the M1343’s knit panels is a post-production surface finish — applied after the garment is constructed, directly onto the Fineness 3 knit inserts. The result is a surface that reads as lacquered or wet-look in quality, but retains the texture and flexibility of the underlying knit. The iridescent quality of the spray means the panels shift in colour and depth depending on the angle of light — appearing almost black in flat light, and revealing dark, complex tones in directional or natural light. This is not a print, not a coating, and not a dye: it is a treatment that transforms the surface of the textile while preserving its structure. Each piece is treated by hand, making every garment unique.

How to Wear It

• Total Black, Maximum Contrast: With wide-leg black cargo trousers and leather boots — the spray panels read as the focal point against a matte monochrome base.
• Unisex Editorial: Oversized on a female frame with drop-crotch trousers and chunky-soled footwear, as styled in the campaign imagery.
• Hood Up: The oversized hood transforms the silhouette — pair with minimal trousers to let the top half dominate.
• Layered: Over a fitted turtleneck or long-sleeve base layer, with the spray panels creating a lacquered contrast against the matte base.

Care Instructions

• Hand wash cold or dry clean recommended — to preserve the spray treatment on the knit panels
• Do not machine wash — agitation may affect the spray finish over time
• Do not tumble dry — lay flat or hang to dry away from direct heat
• Do not iron on spray-treated panels — heat may alter the surface finish
• Store hung or folded — avoid prolonged compression of the spray-treated areas
