These washable nursing pads are the comfortable, eco-conscious choice in nursing gear! OnGuard™ nursing pads are recommended by Lactation Consultants for their superior quality and affordability. They are available in 2 sizes and 2 styles: pure organic cotton or luxuriously soft organic merino wool. (Organic merino wool is antibacterial and absorbs up to 30% of its weight in moisture before feeling wet. It also keeps the breast warm during use helping to decrease the risk of nursing difficulties.)
