Willow 3.0 is the only wearable pump that offers total mobility—360 degrees of motion enabled by our patented, continuous latch suction technology and Spill-Proof Milk Bags. Other wearable pumps imitate Willow 3.0’s in-bra design, but leak if you move too much.
It's also the only in-bra wearable pump that offers two ways to pump and store your milk - choose from self-sealing Milk Bags or Containers.
