Thank you for viewing. This is a button-up blouson from Uniqlo. The simple design is perfect for casual styles. It has side pockets and an inner pocket, making it highly functional! The entire back is mesh, so you should be able to stay comfortable without getting stuffy. The color looks gray, but it's likely khaki (light). It's difficult to accurately convey the color, and I apologize, but please refrain from purchasing if you are unsure to avoid any issues. - Design: Button-up - Style: Casual - Back Style: Simple - Pockets: Side pockets Inner pocket x1 Although there are no tags, it is a new and unused item. If anyone is interested, please consider purchasing.
