This is a khaki half-zip nylon jacket from the brand VANTAGE. I bought it at a used clothing store for around 6,000 to 7,000 yen. The size is between a standard M and L. It's lightweight and made of breathable material, so you can wear a hoodie underneath and use it on rainy days. There are some minor stains, but it's in generally good used condition and can be worn without worry. The patch on the sleeve gives it a military feel, which is cute.
