This is a US Navy training T-shirt. I purchased it at a used clothing store. The body is made by SOFFE in the USA. The size is M, but please refer to the details below. It's 100% polyester, so it's quick-drying. From training to everyday wear, the chest and back prints are reflective. There is some pilling due to the material, but there are no scratches or stains. Feel free to comment if you have any questions or would like additional images.
