SOFT, ABSORBENT, AND HYPOALLERGENIC - Made of the softest bamboo plus wicking microfiber, these nursing pads are more absorbent and durable than cotton, and they offer superior comfort for chafed or sore nipples and sensitive skin. SAFE FOR MOM & BABY - These pads have a 100% organic bamboo inner layer, a high-absorbency microfiber middle layer for wicking moisture away, and an outer layer made of waterproof PUL fabric for protecting from leaks. ENVIRONMENTALLY FRIENDLY - Unlike disposable nursing pads, these washable breast pads can be reused over and over again. Simply machine wash and tumble dry between uses. CONTOURED SHAPE FITS INSIDE NURSING BRAS - These breast pads measure 4.5 inches in diameter and feature a clever contoured shape to fit smoothly and discreetly in your nursing bras.
