3xlt and 4xlt only ordered because I read the difference in the reviews. These will be sports shirts, size 3xlt fits perfectly. I'm 6ft 1in and am currently around 295 due to injuries and Covid weight (no excuses it's grind time). Broad shoulders and chest, some belly but not a big flabby belly. Under normal circumstances, a solid linebacker physique, but no six pack, just a tight core. Haven't washed yet but so far so good. 4 xlt is of course a bit bigger, but not too big. If they shrink at all 4 xlt would be fine if it fits like 3xlt until I lose weight and 3xlt is good after that. Hope this helps someone
