This is an H&M half-zip knit sweater I bought new a few years ago. The size is XS, but it fits like a Japanese size S to M. Made of 90% acrylic and 10% nylon. The color is dark gray. It has elbow patches on both elbows, which are sturdy. Measurements taken with the garment laid flat are as follows: Width: 44cm Length: 64cm Sleeve length (from center back neck): 74cm Length and sleeve length are measured from the base of the collar. Please note that these measurements are approximate due to being taken by hand. I've worn it a few times since I bought it, but there are no noticeable stains or tears. Please check the photos and consider purchasing.
