This black Nike Dri-Fit long-sleeve t-shirt is made from a very thin material and is perfect for layering under your running gear, padding, etc.   It works great for a light shirt for a run or just to throw on to lounge.  I wouldn't really call it compressive, just comfortable.   It's only been worn a handful of times, in fact I'm not sure it's ever been worn.  PB logo looks awkward in the photo, but that's how it came.
