Willow Go™ Pump and Container Bundle

Willow Go offers the best of both worlds — built with hospital-grade suction and a comfortable tug-and-release latch (the same you’re used to if you’ve used other wearables or a traditional pump) while fitting fully in-bra. It’s proof that you don’t need to sacrifice comfort and convenience for output.

Learn more about why Willow is different from other pumps, or check out our blog post for more information on how Willow pumps differ from manual and electric breast pumps.

Both pumps are fully in-bra with no bulky motors or cords, making it possible to pump on the go, and controllable via the Willow app. However, Willow Go cannot be controlled via Apple Watch, while Willow 3.0 can.

Willow Go is the perfect pump for every day with a 100% comfort rating and a tug-and-release latch designed for optimal output. Moms who use Willow Go say that they get as much, if not more milk when compared to other traditional or wearable pumps.

Unlike Willow 3.0, which offers moms 100% leak-proof mobility, Willow Go is leak-proof up to 45° — meaning you can still move around, but cannot use it while laying down or bending all the way over.

Willow 3.0 offers the option to pump into 4 oz milk bags or reusable containers, while Willow Go is only compatible with reusable containers. However, Willow Go offers a higher capacity option than Willow 3.0 — up to 7 oz per side.

Most moms get up to 40% (as much as $159) off their Willow 3.0 pump and accessories. Some women are able to obtain full or partial reimbursement for their Willow Pump and accessories through insurance. Use our Insurance Verifier to check your coverage and purchase your discounted pump.

Yes, you can. Simply pay for your breast pump and accessories using your FSA/HSA debit card at checkout, or pay with another credit card and submit your receipt to your plan administrator for reimbursement.

Yes! We partner with Affirm to offer split pay and installment payment plans for Willow pumps. Learn more about our financing options.

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 our pumps to optimize milk expression.

Willow Go offers maximum suction of up to -280 mmHG per side. It’s also a closed-system pump, just like hospital-grade pumps, to keep your breast milk separate from the pump mechanisms for cleanliness and hygiene.

The Willow Go pump is a single-user device that should not be shared between moms.

No. But Willow Go works best with a pumping or nursing bra that’s snug and stretchy (no underwire!) with full coverage so just the top of the pumps peek out. Avoid bras with underwire or padding. The Daily Pumping Bra is designed specifically for Willow pumps, making it a great choice for optimal comfort and output.

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.

Yes! Willow Go is covered under a 12 month warranty from the purchase date. Accessories - all replaceable pump parts including but not limited to flanges, containers, diaphragms, duckbills, chargers and sizing inserts- are covered under a 90 day warranty. Please review our warranty policy.

Breast pumps and accessories are regulated as single-user products, and cannot be returned once the safety seal has been broken. See our returns policy.

• You can return an unopened Willow Pump within 60 days of the purchase date. If you decide to return your unopened pump or accessories, you must contact us to start the return process and to obtain a RMA number. Please review our return policies.
