Blue washable period shorty. The full back protection length inside the brief is 38cm which make it very safe for the night, you can lye down and dream without fear. That style is suitable for super high flux with 3 layers of absorption fabric. You can use Moon alone in replacement of night pad/night disposable brief ( which is what Culottee recommends) or with extra protection tampon or cup. Thanks to the very soft and stretchable fabric, Moon is very comfortable and can fit all bodies. The fabric outside is blue and the inside cotton fabric is black. It is odorless and easy to wash.¬†Culottee underwear can also be used as leak-proof panties to prevent urinary incontinence.
