This is a Reebok T-shirt. It is new and has only been tried on. The color is very beautiful. I am selling it because the size did not fit. It is labeled as size OT, but it actually fits like a size S. When laid flat, the chest circumference is 40 cm. The length is 58 cm in the front and 63 cm in the back, with a design that is slightly longer in the back. It is also made of mesh, so it is breathable. A slim-fit T-shirt made with lightweight, soft-touch material. Features reflective prints for visibility during nighttime runs. Made with Speedwick material for excellent sweat absorption and quick-drying functionality.
