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.

Comfortable and Stylish
Size: Large, Color: Black
Bought for the husband and he loves it. Comfortable and nice. Says he would pair it with jeans. Flattering. Color is great. Not sure yet on fading and wear, haven’t had it long enough.
