The perfect accompaniment to our FourthWear Postpartum Bralette— a set of soft, moldable ice/heat packs specially designed to surround the nipple and provide instant and sustained relief from the tenderness and tightness associated with engorgement, breastfeeding, surgery 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 on hand during your Fourth Trimester— one for storing in the freezer to alleviate tenderness and swelling and one for heating to ease engorgement. Store in the freezer for cooling comfort. Microwave for 15 second intervals for heat therapy. Do not machine wash. When needed, clean by rinsing in cold water with mild soap and let air dry completely before warming or freezing.
