The Medela PersonalFit Flex Breast Shields 2 Pack is a set of replacement breast shields (flanges) for your Medela breast pump, designed to help you fine-tune the way the pump sits against your body. If your current shields feel like the wrong fit, you've lost or worn a set, or you simply want a spare pair on rotation, this is the part that connects your breast to the pump and shapes how comfortable and efficient each session feels.
Developed with input from research scientists and breastfeeding mums, the PersonalFit Flex shield is made to adapt to your shape — which matters, because your breast shape can change over your feeding journey. The oval opening can be rotated a full 360° so you can settle into the position that feels most comfortable, and the 105° angle is designed to improve fit and support milk flow. A soft, smooth, flexible rim sits against the skin, and the shields are made from BPA-free materials.
How it works
- Adaptable oval shape: The oval funnel can be rotated 360°, letting you turn the shield to the angle that seats most comfortably rather than being fixed in one position.
- 105° opening angle: The wider angle is designed to improve how the shield fits, which helps support your milk flow during expression.
- Flexible rim: The soft, smooth rim is shaped to adapt to your body and is designed to help prevent compression of the milk ducts as you pump.
Getting the right size
Breast shield sizing is personal and isn't reliably guessed from bra size — the right funnel size is the one that fits your nipple comfortably as it draws through the tunnel. PersonalFit Flex shields are available in four funnel sizes: 21 mm, 24 mm, 27 mm and 30 mm. Choosing the size that matches you makes a real difference to comfort, so it's worth checking your measurement before you buy.
Best For
The Medela PersonalFit Flex Breast Shields are a great option for parents who:
- Use a compatible Medela pump and want to replace worn shields or keep a spare pair for a quicker cleaning turnaround
- Are finding their current shields uncomfortable and want to adjust the fit and angle
- Want to move to a different funnel size as their needs change
Comes as a pair with instructions for use, so you have a matched set ready for single or double pumping.
Please confirm compatibility with your specific Medela pump model before ordering, as connectors and shields can differ between generations.
