Yes, this shirt is form fitting and comfortable.  The sleeves are cut in a way to accentuate upper arm development.  I ordered the blue color, which looks very nice.

Why only three stars from me, then?  Well, despite the item description stating that this shirt is tagless it does, in fact, have a tag.  I suppose the manufacturer meant there is no tag at the back of the neckline, and that is true.  What wasn't disclosed is that there is a much larger Calvin Klein logo tag that's sewn into the left-hand side seam just below the waist line that sticks out from the garmet.  If you tuck your t-shirts in, then this tag will be hidden and might not bother you since it's on the outside of the garment.  If you prefer to leave your shirt untucked, however, there will be a 2" long tag visible to you and anyone else checking you out.  This makes an otherwise attractive shirt much less attractive to me.
