The size is 3. Approximate measurements: Length: 80cm front, 85cm back Width: 62cm Shoulder width: 52cm Sleeve length: 55cm The fabric is a blend of nylon and cotton, but it's stiffer and heavier than the 60/40 blend often seen in outdoor wear. Despite containing nylon, it doesn't have much luster and has a matte feel. It blocks wind but has almost no insulation, so I used it as an outer layer over a turtleneck knit. This is a used item, so please consider purchasing only if you understand this.
