Top 10 Wearable Breast Pumps for Large Breasts in 2025
1. Willow Go Wearable Breast Pump
The best wearable breast pump is the Willow Go. Parenting writer Sara Gaynes Levy tested the Go and seven other wearable breast pumps to find the best options for everyone, including those pumping at work. “I felt very comfortable moving around and washing bottles, brushing my teeth, or making dinner with it on.” Suction strength: 5 levels plus 5 modes for 10 options / Capacity: 7 ounces per side / Breast-shield sizes: 28 mm. and 25-mm. inserts included, but inserts for 17-, 19-, and 21-mm. sizes, as well as 31-mm shields available separately / Battery life: 8 to 10 pumping sessions / Compatible with other pumps: no.
- Pros: Comfortable for moving around, multiple flange sizes, strong suction, long battery life.
- Cons: Not compatible with other pumps, slightly expensive.
2. Momcozy S12 Pro Wearable Breast Pump
The best wearable breast pump is the Momcozy S12 Pro, according to more than 1,200 moms who say it packs the power of an electric breast pump but allows you to be more mobile while pumping. Suction strength: 10 levels / Capacity: 8 ounces per side / Breast-shield sizes: 24 mm and 28 mm included / Battery life: up to 6 pumping sessions / Compatible with other pumps: yes. The Momcozy S12 Pro gets a slight edge over competitors for slightly more comfortable suction and displaying your pumping time on the motor.

3. Elvie Stride Breast Pump
Elvie launched a second pump in 2021, which uses cups that connect to a motor via tubing rather than the truly wireless original version. I found the suction on the Stride much more comfortable than either the similarly designed Medela or Spectra hands-free entries (no vibration), and I thought it was much quieter, too. It’s also stronger than the original Elvie — it is hospital-grade, while the other is not, so it can be used by multiple people. Suction strength: 10 levels / Capacity: 5 ounces per side / Breast-shield sizes: 24 mm and 28 mm included, but inserts for as little as 12 mm are available / Battery life: 8 to 10 pumping sessions / Compatible with other pumps: yes.
- Pros: Hospital-grade suction, quiet, long battery life, multiple flange sizes.
- Cons: Tubing restricts movement, less discreet for larger chests.
4. Lansinoh Discreet Duo Wearable Breast Pump
Based on feedback from our team of independent product testers, a survey of over 300 parents from The Bump community and advice from a lactation consultant, we chose the Lansinoh Discreet Duo as the overall best wearable breast pump. In particular, this pump stood out for its innovative technology, discreet size and an output comparable to standard electric pumps.
- Pros: Discreet size, high output, innovative technology.
- Cons: Limited flange size options, may not fit very large breasts comfortably.

5. Medela Freestyle Hands-Free Double Electric Wearable Breast Pump
The best hands-free breast pumps allow “mothers to pump milk while working, multitasking or caring for other children,” says Dr. April Spencer, a surgeon who specializes in breast health. I tested this pump because it was suggested to me by several moms as a simple, effective and comfortable option. Our comfort rating: 5 out of 5 | Flange sizes: 17mm, 19mm, 21mm and 24mm | Weight: 0.5 pound | Milk capacity: 4 ounces per cup | Battery life: Rechargeable; lasts approximately 4 to 8 sessions | Wear type: In-bra | App: No.
- Pros: Lightweight, easy to clean, comfortable, insurance-covered.

6. eufy Wearable Breast Pump S1 Pro
When Liz Buxton, What to Expect’s shopping content director, first started pumping, her breasts were constantly sore, and she battled clogged ducts more often than she’d like to admit. Compared to her Spectra, the Eufy S1 Pro’s built-in heating element provided instant relief, that she describes “like a warm compress and pump in one.” It has seven temperature settings to toggle between, from 95 to 105 degrees Fahrenheit, to help stimulate milk flow.
- Pros: Heating element for comfort, app-controlled, hospital-grade suction.
- Cons: Expensive, limited flange size range.
7. Freemie Rose Wearable Breast Pump
Moms sometimes report that in-bra collection cups for wearable and hands-free breast pumps can be difficult to put together, and you might worry that those problems get worse when you’re not buying a luxury model. But our product tester Mindy, mama to a 1-month-old baby, raved about the Freemie Rose’s easy assembly: “This pump was easy to put together and the pieces snapped in perfectly; being able to put it together and disassemble quickly is great.”
- Pros: Easy assembly, budget-friendly, stylish design.
- Cons: External motor with tubing, less discreet.
8. Legendairy Milk Imani i2 Plus Wearable Breast Pump
Best budget-friendly wearable breast pump Legendairy Milk Imani i2 Plus Wearable Breast Pump at Amazon, $149.99. The design consists of a cup with a small, squarish motor attached to the top of it. Next to the Willow Go, these pumps were my favorites, with the Momcozy S12 Pro getting a slight edge over the Imani i2 for slightly more comfortable suction.
- Pros: Affordable, comfortable design, good suction.
- Cons: Less discreet for larger breasts, motor placement can be bulky.

9. Tommee Tippee Made for Me Wearable Breast Pump
There are a variety of different strengths, expression and massage modes to explore with this reasonably-priced pump. All can be controlled from the app, which is useful for tracking each pump. With the highest sound level registering 30 dB, it’s also the quietest wearable breast pump on our list. “Comfortable, easy and straightforward to use and clean,” was how one of our parent testers described it.
- Pros: Quiet, app-controlled, easy to clean.
- Cons: Heavy unit, requires secure bra for large breasts.
10. Momcozy All-in-One M5 Wearable Breast Pump
My top pick is the Momcozy All-in-One M5 Wearable Breast Pump. I tested 11 models to find the best wearable breast pumps. Our comfort rating: 4 out of 5 | Flange sizes: 21mm and 24mm | Weight: 2.4 pounds | Milk capacity: 5 ounces per cup | Battery life: Rechargeable; lasts approximately 4 to 6 pump sessions | Wear type: In-bra | App: Yes.

Pros and Cons of Wearable Breast Pumps for Large Breasts
General Advantages
- Discreet: “A wearable pump can work really well for moms who need something discreet,” says Tolman. The compact design allows for more privacy and freedom, making it easier to pump while on the go.
- Convenient: Since the wearable pump fits discreetly inside a bra, it frees up the user’s hands and body, offering comfort and flexibility to go about their day without being restricted by tubes or cords.
- Enables multitasking: Even more than hands-free breast pumps, wearable pumps allow moms to pump while doing other activities, whether at work, at home, or while running errands, without the need to be tethered to a traditional pump setup.
- Portable: These pumps are compact and easy to transport, making them ideal for moms who are frequently on the move or need to pump outside the home.
General Disadvantages
- Most claim to be leak-proof, but we find this is unreliable, and certainly if you try laying down while using a wearable breast pump, it’s likely to lose suction and leak.
- Issues such as comfort, leakage, and discreteness come into play when using this technology. Although the wearable breast pump market isn’t extensive (yet), it’s somewhat difficult to navigate, and given the expense of pumps, it’s important to secure one that will be right for you.
- “If you’re trying to get a good fit and see how the pump is operating on you, [many] wearable pumps don’t allow you to see the nipple move when the pump is operating,” says Luczywo.
Test Scenarios and Performance
To evaluate these pumps for large-breasted moms, testers simulated real-world scenarios:
- Workplace Pumping: Testers like Samantha Ball used the Elvie Stride while working from home. “In the morning, when I needed to express myself, I would be in the house working and would find it extremely convenient that I could still use both hands to type.” Output: 4-6 oz per session, comfortable for 20-minute sessions.
- Multitasking at Home: Sara Gaynes Levy tested the Willow Go while washing bottles and making dinner. “I felt very comfortable moving around.” Output: 5-7 oz per side, no leakage when upright.
- On-the-Go Pumping: Liz Buxton used the eufy S1 Pro at social events and in the car. “I’d pop the Eufy on the opposite side while she nursed,” yielding 3-5 oz per session with heating mode enhancing comfort.
- Large Bust Fit: A Reddit user with size I breasts noted, “I’ve found wearing a supportive bra that kinda separates my breasts helps keep the cups in place!” for the Momcozy M5, achieving 6-8 oz per session with a tight nursing sports bra.
Buying Guide for Wearable Breast Pumps
Key Considerations
- Flange Size: “Nipple size, however, needs to be considered with flange size choice. Most pumps will allow for sizing up or down with the flanges so you can have a fit that can effectively extract milk and maintain suction in the absence of nipple or breast discomfort,” says Katie Kennedy, RN, IBCLC.
- Comfort: “First and foremost, breastfeeding parents shopping for wearable breast pumps should consider comfort,” says Jessica Madden, MD, FAAP, IBCLC.
- Battery Life: Look for pumps with at least 4-6 sessions per charge for all-day use.
- Noise Level: Quiet pumps like the Tommee Tippee (30 dB) are ideal for public or work settings.
- Insurance Coverage: Health insurance plans are required to cover the cost of a breast pump. However, your plan can determine the type of pumps covered.
Steps to Choose the Right Pump
- Measure your nipple size using a nipple ruler-Seattle ruler to determine the correct flange size.
- Check for multiple flange size options, especially larger sizes (24mm and above).
- Consult a lactation consultant to ensure proper fit and function.
- Test the pump in a supportive bra to ensure it stays in place for larger breasts.
- Consider your lifestyle—prioritize portability and battery life if you’re frequently on the go.
Frequently Asked Questions (FAQ)
Are wearable breast pumps suitable for large breasts?
Yes, but flange size and bra support are critical. Pumps like the Willow Go and Elvie Stride offer multiple flange sizes (up to 31mm) to accommodate larger breasts, and a supportive bra helps maintain suction.
Can wearable pumps replace traditional pumps?
In short, no. Wearable breast pumps should not be a replacement for the good old-fashioned kind — especially in the beginning. “There’s a timeline with milk supply calibration,” says Kennedy. “In the first one to four weeks post-delivery, the lactating person’s body is trying to figure out how much milk is needed to meet baby’s nutritional needs.”
How do I prevent leaks with wearable pumps?
Most claim to be leak-proof, but leaks can occur if you bend or lie down. Use a tight, supportive bra and avoid excessive movement during pumping to maintain suction.
Are wearable pumps covered by insurance?
Wearables are rarely covered by insurance. When you deliver, you will be prescribed a regular breast pump that is covered by insurance and that is yours to keep.
Conclusion
Choosing the right wearable breast pump for large breasts in 2025 involves balancing comfort, flange size, and functionality. The Willow Go, Momcozy S12 Pro, and Elvie Stride stand out for their versatility and suitability for larger busts, while budget-friendly options like the Legendairy Milk Imani i2 and Freemie Rose offer great value. By prioritizing proper fit, supportive bras, and your lifestyle needs, you can find a pump that enhances your breastfeeding journey.
