These innovative flanges, made for us by Pumpin' Pal, fit into your flange set and eliminate constriction of milk ducts to promote better flow and reduce irritation to the nipple area. They also allow you to sit back in a reclining position while pumping and are considerably more comfortable than traditional flanges for most women. Larger-breasted women may find Super Shields more comfortable than our standard flanges too. Fits into your flange or flange set (part#762) and not into the flange base. Also available in Medium B/C Cup (23-29mm) and Large C/D Cup (29-35mm).
