PersonalFit Flex™ Breast Shield
It’s a whole new pumping experience, personalised to you.
The new PersonalFit Flex™ breast shield was developed with the help of a team of research scientists and breastfeeding mums. It’s designed to easily adapt to your shape, and encourages your milk flow by helping prevent compression of the milk ducts. This makes it easier for every mum to find the pumping position that’s most comfortable for her. The result? More comfortable, more efficient expression, shaped around you.
Our research scientists tested the PersonalFit Flex™ breast shield in four clinical studies with breastfeeding mums. Across more than 1,000 pumping sessions, they proved it delivered more comfort and efficiency. Like every Medela product, our Flex™ breast pumps are designed to make breastfeeding easier, so you can feed your baby with your amazing milk for longer.
PersonalFit Flex breast shield is compatible with all Medela breast pumps (use the original connector that came with your Medela breast pump).

FAQ
What are the PersonalFit Flex™ Breast Shields made of?
Medela PersonalFit Flex™ Breast Shields are made of food grade Polypropylene (PP) and Thermoplastic elastomers (TPE).
Is the material safe for mom and baby?
Yes, the material is made without BPA, natural rubber latex and phthalates.
How should I clean my PersonalFit Flex™ Breast Shields?
The PersonalFit Flex Breast Shields should be washed and sanitized prior to first use. They should continue to be washed after each use and sanitized once daily. Cleaning instructions for the PersonalFit Flex Breast Shields are the same as the cleaning instructions for your other breast pump parts that come in contact with your breast or breast milk; please refer to the breast pump instructions for use for detailed cleaning instructions.
How does the PersonalFit Flex™ Breast Shield yield more milk vs the traditional, 90 degree shields?
The new 105° opening angle and oval shape of the PersonalFit Flex breast shields allows more flexibility for mom to position the shield in different ways while she pumps, based on what’s comfortable for her. When let-down occurs, mom’s milk ducts get bigger – the new shape and angle allows the milk to flow more freely. Changing the opening angle of the flange from 90 degrees to 105 degrees made a difference; it better matched the contour of the breast and reduced compression of the milk ducts, which allows milk to flow more freely through them. This change resulted in increased volume of milk expressed during a pump session - 11.8 percent more overall on average. The 11.8 percent is the average but every mom’s personal experience will differ.
What breast pumps can you use the shield with?
PersonalFit Flex™ Breast Shields can be used with all Medela breast pumps. Make sure you use the original connector that came with your Medela breast pump. (*Only the Flex breast shield can work with all Medela breast pumps. Flex connector can only be used with Medela Swing Flex, Swing Maxi Flex and Freestyle Flex breast pump.)
