Fits snug size up
Size: 4X-Large, Color: Grey W/ Black Dots
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.
