The Hegen Wearable Breast Pump comes with default flange size of 28mm and 22mm Flange Inserts. There are 4 other Flange Insert sizes available (sold separately): 16mm, 19mm and 25mm.
Choosing the right size helps ensure comfort and effective suction during pumping. While the default 22mm fits many mums, nipple size can change throughout your breastfeeding journey, so some may need additional inserts for the best fit. We recommend measuring your nipples after week 35 of pregnancy for the most accurate sizing.
If you’re unsure about your size, our Customer Success team is happy to assist with nipple measurement and sizing guidance.
