PersonalFit Flex™ Breast Shields

Shaped Around You. PersonalFit™ Breast shields play a key role in pumping comfort and efficiency. That’s why Medela incorporated the new FLEX™ Technology that’s shaped around you so you can easily adjust the way your breast shield fits to find the most comfortable pumping position with the PersonalFit Flex™ Breast Shields.

PersonalFit Flex™ Membranes

PersonalFit Flex™ Membranes are extra membranes for your PersonalFit Flex Connectors - included with Medela’s Freestyle Flex™, Swing Maxi™, and Pump In Style® with MaxFlow™ Breast Pumps. Be sure to examine your pump parts regularly, if you notice damage or extensive wear replace immediately. Medela recommends replacing your membranes every 3 – 6 months, depending on your pumping frequency.
