Measurements refer to body size, not garment dimensions
Please note: a Jack Wolfskin size Small is a European/ German size 36 / 38 which is a UK size 8 – 10. Jack Wolfskin Women’s size Medium is a European/ German size 40 which is a UK size 12. Jack Wolfskin Women’s size Large is a European/ German size 42 – 44 which is a UK size 14 -16.
If your body measurements are midway between 2 sizes, go for the smaller size for a slimmer, more snug fit or
for the larger size for a loose, more relaxed fit.
