- Alondra A.Verified BuyerI recommend this productRated 5 out of 5 stars10 minutes agoReally convenient.
I’ve had other wireless pumps before but they were always so bulky. I love the shape of these and the small opening at the top that starts as a slow flow first to avoid spills. I feel like I get the same output as I do with my hospital grade but in less time. I love my willow go!

The pump is very nice has a beautiful sleep design. I haven't had any issues with pumping even used a sports bra and it still worked wonderfully. Only downside I wish they would include smaller inserts for the pumps.

I wanted to love this pump so much, but I just don’t. It constantly loses suction and I always triple check to make sure parts are on right. It is not worth the price point for me.

- Brandy Z.Verified ReviewerI recommend this productRated 5 out of 5 stars1 week agoSo convenient for on the go moms!
These have great suction and the charge last for about 5ish pumps which is great for a mom who may be out and about all day like me! Parts are easy to clean and it’s easy to poor once done pumping. I love all my Willow products!

Frequently Asked Questions

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 360 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 360, 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 360 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 360 — up to 7 oz per side.
Check out our comparison page for more, or take our pump quiz to decide which pump is right for you.
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.
As you navigate through this process, start with our guide on how to get a breast pump covered by your insurance. It gives you all the questions that you need to take to your insurance provider to understand how to obtain coverage and the costs involved.
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.
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.
Since breast pumps are single-user devices, use by more than one person, including purchasing second hand, will invalidate the warranty. Please keep your original proof of purchase from onewillow.com or an authorized retailer as it is required to exercise your warranty.
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.
- Only products purchased from onewillow.com may be returned directly to us. For products purchased from our retail partners, please follow their instructions.• Willow pumps are single-user medical devices and returns must be new, unopened (no seals broken), unused, and in the original packaging.
