The Sportsman's Guide Cotton Shirt

Amazing look and feel to this large shirt. Only tag indicates The Sportman's Guide St. Paul, MN RN 80461. Upon researching it looks like it is a variation of this shirt: https://www.sportsmansguide.com/product/index/mountain-hardwear-men039s-granite-peak-jacquard-flannel-shirt?a=2245874 The shirt is heavy and dense and feels like a wool / cotton blend, however, if it is the above shirt, it's 100% cotton. There is no label that indicated the material nor the size. I can say for sure it is very heavy, comfortable and large (Measurements below). Please note I am not saying this is 100% cotton but it appears to be and I estimate it to be a size 3XL or 4XL. Any larger man who likes a very hearty shirt will love this. Very good condition, no issues. Measurements: Pit to Pit: 33 inches Sleeve: 39 inches (center of back of neck to end of sleeve) Total Height: 36 inches
