Ultimate Opaque, the name pretty much says it all. You may have gathered that the "opaque" part means that these stockings are lushly thick, soft and supple, and give saturated full coverage in all colors. What you might not have gathered from the "ultimate" part, though, is that instead of a traditional skinny elastic waistband (also known as: "torture devices" and "sausage makers"), these stockings have the ultimate luxury: a wide band of nylon and spandex at the waist to smooth and slenderize while never digging in. Ultimate Opaque. Waistband: 72% nylon, 28% spandex; Legs: 90% nylon, 10% spandex. Hand wash in cold water, do not bleach, line dry.
