the sizes would have to be checked again. In a clothing size 38/40, I usually wear, the jacket should fit in size L, while wearing only a thin under-shirt underneath. Unfortunately, the jacket is slim cut that to zip close even an inch is missing. So would Gr itself. XL do not fit (keyword: Pellwurst). Otherwise: The jacket itself is great! Stable, slightly thicker cotton, brushed inside, so the jacket is really cuddly. Right long arms that do not bother me though because I have long arms.
