Willow Go is an electric wearable pump known for its one-of-a-kind design that’s engineered for more comfort and optimal milk output. It has a longer, smoother flange tunnel than other brand wearables; a unique internal circular motor; hospital-grade suction; and a tug-and-release pattern that mimics your baby’s natural rhythm.

Willow 360 is an electric wearable pump renowned for its 100% leakproof mobility, so you can pump in any position, even while laying down or bending all the way over. It has Apple Watch connectivity and a continuous latch, making it optimal for moms who work in the medical and first-responder fields.

Willow Sync is our insurance-only wearable breast pump, thoughtfully engineered to give you all the Willow innovation you love at a price you’ll love more. It’s inspired by the award-winning design of Willow Go, with overlapping features like a longer, smoother flange tunnel; a unique internal circular motor; hospital-grade suction; and a tug-and-release pattern that mimics your baby’s natural rhythm. A few differences, however, are that Sync has only one motor and controls on one side, and uses tubing to connect the pump to the pump cup. Tubing length can be customized to your preference.

All Willow users have access to the Willow app, which connects moms to our science-backed articles, postpartum resources, and feeding experts.
