Note that, unless the repro manufacturers have changed the material they use, true breathable Comfortweave is not used. In the past, each had been using a stamped solid material that has a Comfortweave-like appearance.

Here are three samples (front and back) I collected eleven years ago when I did mine. Real Comfortweave on the left and two versions of the material they were using for the repro covers center and right. You may want to get manufacturer/vendor samples today to help you decide which you like best.

Back then, some real Comfortweave and matching Madrid vinyl was still available at SMS Fabrics, so I had mine made using that.
