Tommy Bahama polo shirt, sz M (tag says L see desc), NWT $99, feels like cool tk

Tommy Bahama polo shirt, sz M (tag says L), I’m 5’8”, 150 lbs for reference and normally wear a medium. This fits me perfectly. Armpit to armpit is 21”, middle of shoulder down is 28”. If your buying it as a large, it would work, but will definitely be form fitting. Awesome material! Please see pics for breakdown of material. It feels like that cool technology. Would be an awesome shirt for the golf course, a day on the boat or beach or just hanging out. Nice light grey/silver color. Quality made, quality stitching (which looks like it might be reflective), any questions just ask. Thank you for looking!
