The perfect accompaniment to our FourthWear Postpartum Bralette— a set of soft, moldable ice and heat therapy packs specially designed to surround the nipple and provide instant and sustained relief from the breast tenderness and chest tightness associated with breast engorgement, breastfeeding, prenatal and postnatal surgery, mastitis and clogged ducts, and more. Each pack measures 8 inches in diameter for full coverage and can be easily folded for stowing or toting. We recommend having 2 sets of Nyssa Breast/Chest Ice/Heat Packs on hand during your Fourth Trimester— one for storing in the freezer to alleviate tenderness and swelling and one for heating to ease breast engorgement.
