Explanation from AI This is a classic "Duck Vest" from Carhartt, a long-established American workwear brand. The model number is likely V01 or 106676. It's made of durable 12-ounce ringspun cotton duck fabric, making it extremely tough. The lining is quilted, providing excellent warmth and cold protection. The tag is faded, so the details are unclear, but is this a vintage item? There is fading on the back, from edge to edge. Or rather, the back is faded? The sides of the armpits might be the original color! Can you tell from the images? There seems to be some fading in other areas as well! For those who understand the current condition!! As it is vintage clothing, there may be some signs of wear. Shoulder width: 45cm Body width: 63cm Length (from bottom of ribbing): 74cm
