I'm 5ft 11in tall, 233#, mostly muscular lol I'm 20#, around abs, broad shoulders, big chest, thick arms to match legs with to show proper vastus, lateralis and medialis development, bodybuilder training, anyway, size xl fits me freely like a perfect jumpsuit, size 2xl is massive and fits the title: nike shirts are very small and shrink under armor it shrinks and as soon as i start sweating , it stretches to hold me looser but not as big as the new carhartt xl which is 2.5 times thicker than nike or under armour. Cotton would be Champion 2xl with Champion on the chest. Feel free to take it
