Photograph a professional male fashion model aged 22 to 26 wearing the Product, shown with the Build and framed as the Framing. Use a clean standing catalog pose with relaxed arms and a confident, natural expression so the top and shorts remain fully visible. Keep the model's masculine silhouette anatomically distinct and well proportioned. Light the scene with a large soft studio source from the front and slightly to one side, creating believable shadows beneath the feet and subtle definition across the garment. Use the Background with an uncluttered retailer-catalog composition and enough negative space around the model. Render the merino texture, fine knit, seams, waistband, hems and natural fabric creases sharply. Skin should show realistic pores and texture, with natural hair and correctly formed hands. Use accurate proportions, restrained campaign retouching and a straight-on eye-level camera view. No text, watermarks, logos, brand marks, price tags, overlays, borders or frames.
Use these details:
Product: "charcoal merino thermal base layer top and matching shorts"
Build: "lean, fit and toned male build"
Background: "plain cool grey studio background"
Framing: "full body"
