I'll see how this shows up here.

Left is original Comfortweave (worn and color-shifted a bit)
Right is the SMS Comfortweave. In person they look the same.

And here are two repro versions available at the time I did mine. One has a much closer appearance to the origianl material but is solid with no venting. Real Comfortweave you can somewhat see through all the tiny breathable holes. (Hence the "weave".)
