E-commerce fabric science photography: close-up of the three-layer composite windproof fabric of a black sheep leather jacket. From top to bottom: black matte sheep leather surface layer, black high-density windproof membrane middle layer, and smooth skin-friendly black knitted lining layer. The three layers are stacked in a stepped manner, with delicate edge stitching and seam details clearly showing each layer's texture: the leather surface has a fine natural grain texture and soft matte finish, the windproof membrane is compact and thin with breathability and windproof performance, the knitted lining is soft, smooth, and skin-friendly without stuffiness. Use white dashed lines to mark the boundaries of each layer, accompanied by clear text labels naming each layer. Background: pure light gray, soft and even side lighting without strong shadows, highlighting leather texture, fabric layers, and craftsmanship details. Overall style: simple and high-end, conveying product features of windproof, wear-resistant, and skin-friendly. 8K high-definition realistic texture.
