A better way to pump
We set out to deliver what pumping moms want most: freedom. After 60 prototypes, the first and only fully mobile wearable breast pump was born.

One of TIME’s 25 Best Inventions
We didn’t just reshape a traditional pump to make it look modern. We reinvented the way a breast pump could function from the inside-out – an innovation that revolutionized the category and earned a spot on TIME’s Best Inventions list. But we didn’t stop there – we continue to redefine what a breast pump can do. Our generation 3 model yields 20% more milk for moms*.

Pumping, Reimagined
Other pumps use a ‘tug and release’ action to create suction. But this isn’t how breastfeeding actually works. Our proprietary, patented technology creates continuous suction similar to a baby’s latch, making Willow the only pump that can promise true, spill-proof mobility for pumping moms.

Continuous latch technology
With a patented suction seal and pumping rhythm designed around how a baby nurses, you get more mobility and no leaks compared to competitors.

gravity-defying, leak-proof mobility in all-in-one wearable design.
