Willow Breast Pumps Through Insurance
About Willow
Willow is the wearable breast pump brand that started it all. Founded in 2014, Willow invented the first fully in-bra wearable breast pump in 2017, giving moms the freedom to pump without cords, bottles, or being stuck in one place. Built by a team of parents and guided by lactation consultants and maternal health experts, every Willow pump is designed around one idea: pumping should fit into your life, not the other way around.
Today, Willow's lineup includes three wearable models — the Willow Sync, Willow Go, and Willow 360 — each offering a different combination of comfort, flexibility, smart features, and mobility. All three are app-connected, clinically tested, FDA cleared, and made without BPA. Whether you're looking for an affordable insurance-friendly option or the most advanced wearable pump on the market, there's a Willow for you.
At 1 Natural Way, we carry the full Willow lineup and make it easy to get yours through insurance. Many plans cover a portion of your Willow pump, and you may be able to use HSA or FSA funds for the remainder. Check your coverage now to find out which Willow models are available through your plan.

What Moms Are Saying About Willow
I love how I they are connected to one motor. You don’t have to worry about turning both motors on. They are not heavy and easy to clean. They come with an app that makes it much easier to use as well. 👌🏼🫶🏼
I used the Willow Go with my second pregnancy and I really liked it, so I got a new set with my third. Willow has some of the best customer service, I have ever dealt with. The ladies who take your calls are so understanding, get the craziness and are so helpful. If you have an issues with pairing, a crack, anything, they will walk you through the reset steps and troubleshoot or just send a replacement part. No hassles or arguing. I like the updates with the stoppers. That will be very helpful. These are really comfortable. I can use in the car or in the office and am less interrupted by wires, tubes, etc. The clean up is so easy and putting the pumps together takes about 6 seconds, which is great. They are not desecrate but any means, you can hear and see them, but if you have a sweater or cover you can easily make it less obvious. They are not loud, just a slight pump and hum. Definitely recommend for a busy mom.
I love the convenience of this pump but I have had a hard time getting the second one to start pumping. I always have to take it apart and put it back. Not sure why because nothing changes
I love the minimal amount of pieces and how easy it looks to clean. The shipping was fast and hassle free too
I love the willow 360 and the ability to move around and bend over without leaking especially during the power pumping sessions.
It’s just as reliable and works just as well as a standard pump! Love the ease and freedom I get while wearing them!
I like that I am able to tuck it in my bra and work throughout the house without leakage. There is a learning curve, but once you set it up a few times it’s easy to use. It is very bulky.
Love it so far! Get great output. A little bulky but better than being hook up to the wall!
Ordering was simple and shipping was prompt.
This is my first wearable and I do love the convenience of this and it’s great to have for on the go. It’s easy to put together and I love that it comes with a little flange measurement tool as it’s super important as it can change through out your pumping journey. I recommend this pump but I do also recommend having a wall pump as well.
It’s great that it’s portable and hands free, but it never fully empties me out. I’ll still feel engorged even after pumping for 40 minutes. It’s pretty annoying to transfer over to a bottle. I feel like I waste milk every transfer. If it’s your first time pump, I wouldn’t recommend it.
Have not used yet as baby has not come but after arrived perfect and quickly. Super excited to use!!!
Which Willow Breast Pump Is Right for You?
All three Willow pumps share the brand's signature in-bra wearable design, app connectivity, and clinically tested comfort. But each model is built for a different set of priorities. Here's a closer look at what makes each one unique so you can find the best fit for your pumping routine.
Willow Sync
Best for: Moms who want Willow's wearable technology at the lowest out-of-pocket cost, especially through insurance.
The Willow Sync is Willow's first pump designed exclusively for insurance access. It uses a single-motor, two-cup design connected by adjustable tubing, giving you the flexibility to pump from one side or both. The tubing is 34 inches long and can be trimmed to your preference for a custom fit.
Despite its more accessible price point, the Sync doesn't compromise on the technology that makes Willow stand out. It features Willow's internal circular motor for better alignment, a 105-degree flange cone angle that's clinically proven to support milk output, and 20 levels of customizable suction up to 245 mmHg per side. The 5 oz containers include splashguards for easy, low-mess milk transfer.
Like all Willow pumps, the Sync is app-controlled, letting you start, stop, and adjust suction right from your phone while tracking your sessions and accessing expert-backed content.
Insurance: Willow Sync is designed as an insurance-first pump. Coverage varies by plan — check your benefits to see if it's available at no cost or at a reduced out-of-pocket price through your plan. View the Willow Sync product page.
| Type | Wearable, in-bra (single-motor, two-cup with tubing) |
|---|---|
| Suction | 20 levels, up to 245 mmHg per side |
| Battery | Up to 3 sessions per charge |
| Milk Storage | 5 oz reusable containers with splashguards |
| App Control | Yes (iOS and Android) |
| Included Flanges | 24 mm flanges + 21 mm sizing inserts |
| Warranty | 12 months on pump; 90 days on accessories |
Willow Go
Best for: Everyday pumping moms who want strong suction, higher milk capacity, and true wireless freedom in a fully in-bra design.
The Willow Go is Willow's best-selling wearable pump, and for good reason. Each side has its own built-in motor — no cords, no tubes, no external hardware. Just tuck the pumps into your nursing bra and go. It's as close to invisible pumping as it gets.
With 15 levels of customizable suction reaching up to 280 mmHg per side, the Willow Go delivers hospital-strength performance in a compact, quiet package. It comes with 5 oz reusable containers, and optional 7 oz containers are available separately for moms who produce more milk or want longer sessions between empties. That gives you up to 14 oz of total capacity per session — one of the highest among wearable pumps.
The Willow Go connects to the Willow app so you can manage sessions, track milk volume, and access expert content and pumping support. Battery life lasts up to three sessions on a single charge, and all parts are dishwasher safe for easy cleanup.

Insurance: The Willow Go is typically available as an upgrade item, meaning insurance covers a portion and you pay the difference. HSA and FSA funds can often be applied. Check your coverage to see your options. View the Willow Go product page.

Willow 360
Best for: Moms who want the most advanced wearable pump available, with leak-proof pumping in any position, real-time milk tracking, and Apple Watch control.
The Willow 360 is Willow's premium wearable pump and one of the most feature-rich breast pumps on the market. Its standout feature is true 360-degree leak-proof mobility when used with Willow's patented self-sealing spill-proof milk bags. That means you can pump lying down, bending over, chasing a toddler, or doing yoga — without losing a drop.
The 360 is also the only Willow pump with real-time milk volume sensing, so you can see exactly how much you're expressing during each session right in the app. Its Smart Suction technology automatically detects letdown and transitions from stimulation to expression mode without you pressing a button. And it's the only Willow model with Apple Watch control, letting you pause, adjust suction, and monitor your session from your wrist.
You get flexibility in how you collect milk, too. The 360 works with both spill-proof milk bags (for full leak-proof freedom) and reusable containers (leak-proof up to 180°). Each holds up to 4 oz per side. The pump automatically shuts off when a bag or container is full.
Every Willow 360 purchase includes access to Willow 360 Care, which provides a one-on-one virtual onboarding session, sizing support, and ongoing guidance to make sure you're getting the most out of your pump.
Insurance: The Willow 360 is typically available as an upgrade item. Many insurance plans cover a portion, and HSA/FSA funds can often be applied toward the remaining cost. Check your coverage to see what's available. View the Willow 360 product page.
| Type | Wearable, fully in-bra (independent dual motors, no tubes) |
|---|---|
| Suction | 7 smart levels, up to 245 mmHg |

Frequently Asked Questions About Willow Breast Pumps
Which Willow breast pump is covered by insurance?
Coverage varies by insurance plan and provider. The Willow Sync is designed specifically as an insurance-first pump and may be fully covered by many plans. The Willow Go and Willow 360 are typically available as upgrade items, meaning insurance covers a portion and you pay the difference. HSA and FSA funds can often be applied. Check your specific coverage at 1naturalway.com/register.
What is the difference between Willow Sync, Willow Go, and Willow 360?
All three are wearable, in-bra pumps with app control, but they're built for different priorities. Willow Sync uses a single motor with adjustable tubing and is designed for insurance accessibility. Willow Go has independent dual motors with no tubes and offers the highest suction (280 mmHg) and optional 7 oz containers for greater capacity. Willow 360 is the premium model with 360-degree leak-proof pumping (with spill-proof bags), real-time milk volume tracking, automatic stimulation-to-expression switching, and Apple Watch control.
Is the Willow 360 really leak-proof?
When used with Willow's patented spill-proof milk bags, the Willow 360 is designed for 360-degree leak-proof pumping in any position — including lying down or bending over. When used with reusable containers instead of bags, it's leak-proof up to 180 degrees.
Can I control my Willow pump from my phone?
Yes. All three Willow pumps connect to the Willow app, which is available for iOS 17+ and Android 10+ with Bluetooth 5.1. You can start and stop sessions, adjust suction, track milk volume, and access expert-backed content. The Willow 360 also supports Apple Watch control (Series 4+, watchOS 10+).

Willow offers 21 mm, 24 mm, and 27 mm flanges, plus sizing inserts for 13 mm, 15 mm, 17 mm, 19 mm, and 21 mm. Most Willow pump kits include 24 mm flanges and 21 mm inserts. Willow also sells a separate sizing kit and provides a sizing guide to help you find the right fit. If you need additional help, our lactation consultants can assist with flange fitting.

Are Willow pump parts compatible across models?

Flanges and sizing inserts may be shared across models, but always verify compatibility for containers, diaphragms, and tubing before purchasing. The Willow Sync uses its own container and tubing system.
Are Willow pumps dishwasher safe?

All Willow pumps include a 12-month warranty on the pump motor from the date of purchase. Accessories such as flanges, containers, diaphragms, duckbill valves, and inserts are covered under a 90-day warranty.
