This is a Uniqlo U half-zip shirt from the 2025 A/W collection. The color is 08 Dark Gray, and the size is M, a golden size. I purchased this but am selling it because I don't think I'll have a chance to wear it. Compared to other half-zip sweatshirts, the collar stands up well and looks great whether open or closed. Also, the fabric feels high-quality and looks expensive, allowing you to dress it up even though it's a casual item. This is a very popular item, so it's first come, first served. Please consider purchasing it.
