Runs a touch larger than other same brand polo's, light and breathable.
Size: 3X-Large, Color: Black
Super ligh, breathable and thin. Stretchy but still leaves room for the dad bod belly and dad bod boobs lol This specific polo runs a bit larger than most of the others by this same company so be aware of that. I am 5'6" - 280lbs and wear a 4xl normally in AZ's but this one fit perfect in a 3xl. Great summer night shirt, just be mindful not to snag it on something and also better to hand wash this as even a gentle cycle has the tendency to cause some damage.

Fits snug size up

I would definitely size up they fit a little snug, overall good quality and it’s tagless which is a plus.
