The product name at the top of the page says 'Cotton Spandex' which is what I was looking for. Description varies by item: 60% Cotton, 40% Polyester, 90% Polyester, 10% Spandex, 95% Cotton, 5% Spandex (I don't like black); nobody is speaking. They should be the same style/design per side, differing only in size and color (this is quite confusing). I couldn't trust any of them though, although what came was exactly as described for the custom style (just no cotton spandex as the title above suggests).
