The AVENT Breast Pads have a unique four layer construction which incorporates a breathable leakproof backing sheet. Moisture is drawn from the front to the back of the pad by a highly absorbent core so that the layers next to the skin stay dry and air circulates more readily reducing the risk of soreness. The design also features an anti-slip backing and a nipple indent for greater comfort. Unique layered construction for ULTRA absorbency comfort and dryness
