Willow

Wearable Breast Pump

Everything you need to pump is right here. With an all-in-one design, Willow™ works quietly inside your bra, collects your milk in a disposable, spill-proof bag, and tracks your volume through the app. Now you can move freely and do things—real things—while you pump.

We're in Beta

Our first wave of pumps is ready! To purchase Willow for $479.99, you'll need to join our Beta Program. Limited spots available.

No more time-outs.

Don't lose another minute tethered to a wall. Willow liberates you from outlets for good so you can pump while you live, work, play, or relax.

How Willow Fits

Willow sits on your breast and is designed to work with a variety of breast shapes. To use Willow, you'll need to have the correct Flange size. Willow comes with 24 mm Flanges (27 mm Flanges are sold separately). You'll also need a full-coverage nursing bra that's stretchy and has a flap.

Why Willow

Simple +
Easy to Clean

Only a few parts to put together and two dishwasher-safe parts to clean for easy setup and fast cleanup.

Quiet

Willow works quietly so you can go ahead and take that conference call without the mute button.

Smart

Our Willow iOS app displays what is happening when you pump. See such things as milk volume, pumping time, and past pumping sessions. Compatible with iPhone 5 or newer.

Effective + Intuitive

Willow senses your let-down and automatically transitions into expression phase based on your body's own unique milk production and timing.

"Once I got the hang of Willow, it felt like a weight lifted off my shoulders. I was almost ready to quit pumping, and finding Willow gave me the willpower to continue. This is a total game changer. I think it would allow women to continue pumping long after they would otherwise stop because of how inconvenient and intrusive other pumps were."

"I got an email from a Willow Coach thanking me for joining Willow, and wanting to set up a phone call to make sure I understood how to use it and to answer any questions. All of that is incredibly user-friendly. It just shows that they really care about their customers."

"By the end of my third day with Willow, I couldn't imagine how I ever used to pump and care for little ones at the same time. It took me several sessions to get the alignment right."

"Willow has been an amazingly empowering experience for me, really supporting my goal to breastfeed my baby for at least one year while having a demanding job. I can now proudly say I am managing to do both—work and breastfeed. If I had to pay for the pump, as well as the milk bags, I would regard that as an investment totally worthwhile."
