The stand-collar jacket has “down” and “cotton” in its display name, but the specification only states 100% polyester for the material. It does not identify the fill, its amount, or a warmth rating. Choose a size for the layer you intend to wear, and confirm the construction separately.

Fit the jacket over an actual layer

Measure a jacket that closes comfortably over your usual knit at chest, shoulder, sleeve and back length. The listed M is 118/53/55/70 cm at those four points; 2XL is 130/57.5/59.5/74.5. That is 12 cm more chest but only 4.5 cm more sleeve and back length. If you need room over a thick sweater, do not assume the next size will add the same amount everywhere. The 1–3 cm manual tolerance also makes a small difference between adjacent sizes less decisive.

Black, Light Grey and Dark Gray are offered. Ask for a current photo of the selected colour showing the collar and inside, plus the shell, lining and filling labels. A raised collar may change how you pair it with a scarf, but its height is not specified. Neither the display name nor the polyester entry proves genuine down, cotton fill, water resistance or a temperature range.
