These shirts are awesome I own 3 of them. They really hide your gut while making your traps and shoulders look well developed. I like my shirts fitted and for my build they are exactly that while not making me look fat.
It's a nice, comfortable shirt. But it fits a bit larger than what I was expecting. However, quality wise, I am impressed.
These are the only shirts I'll wear, I wear them in the gym, as undershirts, with pajamas etc. These are incredibly light weight and breathable, soft comfortable.
