Medela Harmony is the #1 best-selling manual breast pump in the USA. It combines an ergonomic handle for 2-Phase Expression and the unique PersonalFit Flex breast shield that makes your pumping sessions more comfortable and effective. An intuitive and light weight design. Some days you just need a pump you can grab and go. The Medela Harmony breast pump is the manual BPA-free breast pump made for exactly those moments, light, quiet, and ready whenever you are, with no cords, no batteries, and nothing to plug in. Comfort without compromising milk output. Harmony's PersonalFit Flex breast shield has a soft, oval rim that rotates to fit your body, easing pressure so pumping feels comfortable from the first session. This thoughtfully designed shield helps you get more milk than breast pumps with traditional shields. The ergonomic handle sits naturally in one hand, and features a special 2-Phase Expression design that lets you mimic your baby's natural nursing rhythm, a quick motion to start your breast milk flowing, then a slower, fuller pull to express. Have full control over your own rhythm. Express straight into the 5 oz / 150 ml bottle, and when you are done, twist on the lid, and store. Made without BPA and built from soft, food-grade materials, Harmony comes apart in seconds, has few parts to clean, and is dishwasher safe, so you are ready to go again when you need it. Light enough to live in your bag, it is the portable, on-the-go backup that travels to work, daycare, or the next room. Behind it is Medela, the #1 breast pump brand used in hospitals with 60+ years of breastfeeding research and millions of moms who have been right where you are.
