Fieldn’ Forest men’s flannel shirt. Size tag missing. Assume 2XL. See pictures

Fieldn’ Forest men’s flannel shirt. Size tag is missing. I assume 2 XL but have added pictures of pit to pit measurement and sleeve length from pit to cuff so please use those for proper sizing. Shirt has two front pockets, brown elbow patches, and appears to be in decent shape. No flaws seen. Colors are muted brown, blue and green.
