Willow pumps are unique because everything works inside the pump, inside your bra—no external tubes, cords, or dangling bottles. Plus, you don’t have to sacrifice performance. Willow® 3.0 and Willow Go™ offer hospital strength suction comparable to most double-electric and hospital-grade pumps - choose from seven levels of adjustable suction with Willow 3.0, or nine levels with Willow Go. They’re also easy to assemble and clean, and app connected.
