Nixx Nights Peach are designed to fully envelop you while you sleep, keeping you safe and protected from embarrassing period leaks. They are super soft brushed cotton and look like normal underwear. They have a specially designed protective panel that comes up to the front and back of the Nixx waistband, but without any bulk, so you can sleep on your tummy or back without any worries. The inner protective layer is black, so there is no staining. They are designed to manage your heavy flow days without the need for any other sanitary product.
