it's a brand called Newton Trading Co. and the only place I can find them is TJ Maxx. Every other brand I've tried shrinks too damn much and starts looking like a muscle tee.
I have a bunch of them because they're comfortable and I wear them as outer shirts all the time.
sometimes I wear wifebeaters under my "nice" shirts instead. But I always wear either a white tee or a wifebeater under other shirts.
