Willow® 3.0 Wearable Breast Pump

$549.99

Willow 3.0 is the most innovative in-bra pump — giving you 360° mobility so you can pump in any position (no leaks!), and the ability to control your session from your phone or Apple Watch. Because momming is hard... but pumping doesn’t have to be.


Willow 3.0’s hospital-grade suction strength and automatically-adjusting Smart Suction technology results in more comfort, more control, and 20% more milk.* Because you’ve got better things to do than stay plugged into a wall all day.


What makes Willow 3.0 different:

  • Willow 3.0 is the only wearable pump that doesn’t leak. Our patented, continuous latch technology defies gravity to support pumping in any position (even lying down!) when using our leak-proof milk bags
  • The only in-bra pump with the option to pump into spill-proof, self-sealing milk bags or eco-friendly reusable containers (sold separately)
  • It's the only in-bra pump that works with spill-proof, self-sealing milk bags or eco-friendly reusable containers (sold separately), offering unprecedented flexibility
  • Using our app, you can pump even smarter — just tap to start, stop, adjust suction, and track history. Now available on Apple Watch!

Check out these features:

  • Hospital-grade suction up to -245mmHG
  • 7 levels of adjustable suction, with Smart Suction technology that automatically transitions from Stimulation to Expression at letdown and adjusts to help you get more milk
  • Rechargeable battery lasts up to 5 pumping sessions to get you through the day

FAQs

How is Willow® 3.0 different from other wearable pumps?

Willow 3.0 is the only wearable pump that offers total mobility—360 degrees of motion enabled by our patented, continuous latch suction technology and Spill-Proof Milk Bags. Other wearable pumps imitate Willow 3.0’s in-bra design, but leak if you move too much.

It's also the only in-bra wearable pump that offers two ways to pump and store your milk - choose from self-sealing Milk Bags or Containers.

What are the differences between Willow 3.0 and Willow Go?

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.

Is Willow 3.0 covered by insurance?

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.

Can I use my HSA/FSA?

Yes, you can. Simply pay for your breast pump, milk bags 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.

Do you offer financing?

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

Do I need to use Milk Bags with Willow 3.0?

No, Willow 3.0 is the only pump that offers the option to pump into Spill-Proof Milk Bags or Reusable Containers. Milk Bags enable total 360 degree mobility, while Containers offer 180 degree mobility, superior to other wearable pumps.

What are the new features for Willow 3.0?

We’ve re-engineered how Willow pumps to yield more milk per session–and offer more comfort and control. Generation 3.0 has a slower, softer pumping rhythm and a sensitivity setting for comfort, plus new Smart Suction Technology that adjusts based on your preferences to help you get more milk. Compatible with our new app exclusively for Generation 3.0, which offers fast, easy pairing and step-by-step onboarding.

What does the Willow 3.0 app do?

Our easy-to-pair app lets you control your pump and track progress in real time, plus view pumping history. The app is available for iOS 14 and higher and Android OS 10 and higher. Please see list of compatible devices.

What can I do with the Willow 3.0 app for Apple Watch?

Start and pause your pumps, increase and decrease suction, track your pumping session in real time, and check your pumps’ battery levels. When Willow 3.0 isn’t in use, glance down at your watch to see when you last pumped. Willow 3.0 for Apple Watch is compatible with watchOS 8 and above, and Apple Watch Series 3 or later.

Can I pump using my Apple Watch and leave my phone at home?

No. Willow 3.0 for Apple Watch is a companion app, meaning that it uses data from the Willow 3.0 app on your mobile phone. Therefore, your phone will need to remain within ~30 feet of your watch during your session.

Does Willow 3.0 work with larger breast sizes?

Yes. Willow was designed to work with larger breast sizes including G and H bra cups.

We strongly recommend measuring yourself to determine your Willow size as it might be different from other pumps you’ve used. Unsure of your size? Visit our sizing guide or check out our exhaustive guide on how to measure your flange sizewhich includes pro tips from Willow’s lactation consultants.

Do I need a special bra for Willow 3.0?

No. But Willow 3.0 works best with a bra that provides a supportive, snug fit to hold it in place so pumping is even easier on you. We recommend wearing a full-coverage nursing bra that’s stretchy and has a flap. Avoid bras with underwire or padding. Go for maximum comfort and maximum support. The Perfect Pumping Bra has all of the above.

What do you mean by hospital grade suction strength?

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.

Will Willow 3.0 still work if I produce more than four ounces on each side?

Our Spill-Proof Milk Bags and Reusable Containers hold up to 4 oz of milk (8 oz total). Willow 3.0 automatically shuts off when your Milk Bag or Container is full. If you pump more than 4 oz in a single session, you can easily switch out the bag or empty the container and continue pumping.

Does Willow 3.0 have a warranty?

Yes! Willow 3.0 is covered under a 12 month warranty from the purchase date, and pump accessories — all replaceable pump parts including but not limited to flanges, FlexTubes™, containers, milk bags, 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.

Willow cannot be used with any charger that is not provided with the pump or purchased as an accessory from Willow. Usage of third-party charging accessories is unsafe, may cause serious damage to your pump, and will invalidate the warranty.

Can I return Willow 3.0?

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.

2 baby’s on this pump

With Niaomi I pumped every two hours and feed on demand, with that being said I was able to donate 3,000 oz in 4 months.I stopped breast feeding on boob to bottle feeding at 8 months and you’ used my stick milk over 4,000 oz.

5 cubit feet deep freezer almost full

With Kodi’lee I only pump morning and night while he also feeds on demand, now I have almost 1,000oz in 2 months of his life. If it wasn’t for this pump I wouldn’t beable to pump.I have 6 kids in home and I’ma full time collage student as well. I’m always on the go.

I do wish to try the Willow go but money wise i can’t and I’m stuck with the willow 3.0.

Life changer

The Willow pump is a life changer for anyone who doesn’t like to sit still and be strapped to a wall. It helped me continue to pump/breastfeed with my 1st son for at least 9 months esp when going back to work. It’s also a life saver now with my 2nd son as my toddler also wants a lot of attention. It takes time to adjust to the pumps as there is a learning curve but once you get the hang of it, it’s easy. Do yourself a favor and get these pumps. Don’t wait any longer, I regretted waiting the 6 weeks that I did.

Perfect for work

At first I was unsure of this pump, but once I got the hang of it I realized how convenient it is. I mostly use this pump at work because pumping directly into the bags is quick and sanitary. Also until I figured out how to flip to finish and not have the containers leak was a challenge but I finally understand what I was doing wrong! The only con of this is how expensive it is to buy bags and I feel like I’m losing out on some of the milk that gets stuck in the bags when trying to empty them into a bottle.

A fantastic product!

I ordered my Willow 3.0 as a complement for my main pump. I have an older child in addition to my newborn and I needed a pump that freed me up from wall plugs and tubing. Originally, I was intending to use Willow a few times during the day while still using my workhorse pump in the evenings and overnight. However, I have found Willow to be so convenient and effective at draining my breasts that I have completely switched over! Willow gets that last 1/2 ounce that my main pump could never coax out.

A few notes:

1. Sizing IS extremely important. You will likely need to test drive a few flange sizes while adjusting to Willow.

2. Watch all of the instructional videos in advance to familiarize yourself with the technique to using Willow.

3. Look up the Willow adjustment protocol. Some women require time to acclimate their nipples to the different sensation that Willow uses to pull milk. Don’t get discouraged after one day.

All in all, I am extremely pleased with my purchase and will recommend this product to any moms in the market for a breast pump.
