The Medela Swing Breastpump is Medela's smallest and lightest single electric pump. You can pump on the go with this set's options for use. Set the Swing on a tabletop, attach it to your pocket or belt with the clip or hang it from the neck/shoulder strap for the most convenient and comfortable position for you. The comfortable SoftFit breastshield creates a massaging effect while you pump. You'll create more milk in less time with 2-Phase Expression technology and pump more efficiently when you set the device to the Maximum Comfort Vacuum level. In between uses you can keep the pump and accessories neat by storing them in the drawstring bag. All elements of the pump that come into contact with breast milk are BPA free.
