Columbia t-shirt - size probably L

Columbia heather gray short sleeve t-shirt. The fabric content tag is missing, but it’s the dream knit activewear material. The size stamp on the inside collar is worn off, but I’m guessing it’s a large. The pit to pit measurement is 19 1/2” and the length is 26” at the longest. The back scoop is longer than the front. The sleeves have extra detail with a cuff and the Columbia tag stitched on. Scoop neck and additional detail on the back with a seam and special stitching. Even though tags are missing this t-shirt is in mint condition with no picks and no stains. Open to offers :). Smoke free home.
