The Stand Collar Down Jacket is offered in Black and Off White, with a size chart from M to 2XL. Its listing specifies 100% polyester for the material and 90% white duck down for the filling. Those are two different parts of the jacket. The 90% figure describes the listed down proportion; by itself it does not tell you the total amount of fill, fill power, warmth at a particular temperature or rain resistance. If those details determine your purchase, ask for the current garment label and the missing specifications rather than treating the percentage as a weather rating.

Compare the shell, fill and actual layer

The gallery shows a padded stand-collar shape in both offered colors. A scarf appears in one styled image, but the listing does not name it as an included component. If you plan to wear a knit beneath the jacket, first zip a reference jacket over that knit and note where it feels tight. Measure the reference jacket at chest, shoulder, sleeve and back-center length. Then compare those paths with this chart; a model’s stated height of 172 cm and try-on size M do not establish your own fit. The measurement guide explains why comparing a body circumference to a jacket circumference can mislead.

Read the M-to-2XL size steps

The listed chest values are 112, 116, 120 and 124 cm. Shoulder width is 51, 52.2, 53.4 and 54.6 cm; sleeve length is 59, 60.5, 62 and 63.5 cm; back-center length is 69, 71, 73 and 75 cm. Each size step adds 4 cm at the chest, 1.2 cm at the shoulder, 1.5 cm at the sleeve and 2 cm at the back. For example, an L-to-XL change adds 4 cm of listed chest but does not add the same 4 cm at the sleeve. Use the measurement that limits your current jacket, rather than assuming all dimensions expand together. The listing says measurements were taken manually with a possible 1–3 cm difference; ask whether chest is full circumference or doubled flat width before making a close call.

Ask the questions the percentage cannot answer

Request the fill label, total fill weight and any fill-power figure if you need to compare this with another down jacket. Ask what makes up the remaining fill percentage and whether there is a separate lining composition. The page gives no waterproof rating, temperature range or care instructions. Black and Off White are real selectable options; if exact shade or staining concerns matter, request current color photos and the care label. These checks keep the listed composition, the size chart and the missing performance facts in their proper places.
