I own several of the original Covert Shirts which I still use to date. They were made with a mesh lining throughout, full sized cloth lined hidden interior pockets, two front pockets with buttons...one pocket with a pen slot sewn in and apparently a different kind of "cotton." This "Classic" shirt has no interior mesh lining, two small mesh interior pockets, one front pocket with no button and no pen slot. The tag states it is cotton but I find that difficult to believe. On a whole, I would not recommend this to anyone seeking a concealed carry shirt or anyone who believes they are getting the "Classic" covert shirt. It is really a rag with three pockets.
