The Medela PersonalFit Flex™ breast shield was developed with the help of a team of research scientists and breastfeeding moms. It’s designed to easily adapt to your changing shape, and encourages your milk flow by helping prevent compression of the milk ducts. This makes it easier to find the pumping position that’s most comfortable for you. The result? More comfortable, more efficient expression, shaped around you.

Medela's research scientists tested the PersonalFit Flex™ breast shield in four clinical studies with breastfeeding moms. Across more than 1,000 pumping sessions, they proved it delivered more comfort and efficiency. It’s a whole new pumping experience, personalized to you.
