These Hue Run Resistance Sheers are less delicate than other sheers, but with a nice 25 denier sheer appearance, you can feel confidant these will last wear after wear. These are constructed with a control top panty for slimming support, a wide comfortable waistband that lies flat against the body, and an invisible reinforced toe for durability. Made in the USA. 76% Nylon, 24% Spandex. Hand wash in cold water. Do not bleach. Drip dry. Do not iron.
