Willow Go™ Pump and Anywhere Case Bundle

Willow Go™ is unique because, unlike traditional breast pumps, everything works inside the pump, inside your bra—no external tubes, cords, wires, or dangling bottles. This smart, hands-free pump connects to our app for step-by-step onboarding, easy session tracking, and pumping pro tips. Learn more about why Willow or check out our blog post for more information on how Willow pumps differ from manual and electric breast pumps.

Willow 3.0 offers complete, leak-free mobility when pumping with our Spill-Proof Milk Bags. With its gravity-defying continuous latch suction technology, you can pump in any position, from bending over to lying down. Willow Go doesn’t offer as full of a range of motion, but offers the same completely in-bra design and lets you pump totally hands-free and untethered. Willow Go’s “tug and release” suction technology is comparable to traditional pumps and other wearable pump brands.

Willow 3.0 offers more milk storage options. It’s compatible with Spill-Proof Milk Bags and reusable Containers, while Willow Go offers Containers only.

Both pumps are app connected, but Willow 3.0 offers smart pumping that tracks volume in real time and automatically records your session. Check out our comparison page for more, or take our pump quiz to decide which pump is right for you.

Willow Go holds up to 5 oz of milk (10 oz total). If you pump more than 5 oz per side, purchase our 7 oz containers to pump up to 14 oz per session (sold separately).

We know every ounce matters when it comes to pumping and breastfeeding, so we engineer and test our pumps to optimize milk expression and comfort. Willow 3.0 and Willow Go have a wearable, in-bra design, with a suction range and strength that is comparable to traditional double electric and hospital grade pumps. Willow 3.0 offers a proprietary continuous latch suction and unique pumping waveform with up to -245mmHG maximum suction. Willow Go offers maximum suction up to -280mmHG. Willow pumps are closed system pumps, just like hospital grade pumps.

While Willow’s suction strength is equivalent to hospital grade pumps, Willow pumps are single-user and have been clinically tested with established milk supply. Consult your health care provider if you are seeking to initiate lactation with a breast pump.

For your best pumping experience, we recommend a full coverage nursing bra that's stretchy and has a flap - no underwires or padding. It should hold the pumps securely in place when fastened. The Willow Perfect Pumping Bra works great with both Willow 3.0 and Willow Go.

The Willow Go™ App is available for devices that run the following operating systems:

iOS 14 and higher

Android OS 10 and higher (must support Bluetooth 5.1)

Keep in mind, due to the significant number of different Android device models, Willow® cannot guarantee optimal performance of our pumps across all devices.

The Willow Go pump kit includes two USB charging cables which can be used with any standard 5 Volt USB power source. We recommend at least 5 Volt 2 Amp adapters for fastest charging.
