Descente Baseball navy undershirt, size 160. It's fleece-lined, so it should be great for the coming season. For winter - Color: Navy - Size: 160 - Brand: Descente Baseball My family has royal blue. I bought additional royal blue on Mercari, but the colors were slightly different. I think it's probably navy. Please compare using the photos 6 and 7. The brighter color is royal blue. Please check the color carefully before purchasing. *Shown for comparison only. The item is the navy one. It's clean with no name tags, and I think it can still be worn a lot. Thank you for looking.
