Medela's Ultra thin disposable absorbent pads are designed for those times when you experience low to moderate milk loss. Features: Innovative oval shape optimized to fit your chest discreetly. The absorbent polymer core locks in moisture. Five absorption layers in less than 2mm thick. The soft, hypoallergenic lining keeps you comfortable and dry. Flexible leak guard prevents milk from spilling out the sides. They are a discreet way to keep you protected and calm as they are made of a soft, honeycomb-structured non-woven material (similar to that used in baby diapers), so they are comfortable to wear, even if your skin is very sensitive. In fact, they are so comfortable that you may even forget you are wearing them, so remember to change them periodically! Each nursing pad comes individually wrapped, ready for you to slip into your bag and use wherever you go. Safe & Dry Ultra thin disposable absorbent pads are available in packs of 30 or 60 units, individually wrapped.
