7 Best Wearable Breast Pumps That Let You Pump While Doing (Literally) Anything

Voted Best Wearable Breast Pump in the 2026 What to Expect Feeding Awards (and in 2024, too!), the Momcozy S12 Pro Wearable Breast Pump stands out for its efficiency and affordability.

“I’ve been using the Momcozy S12 for a few months now, and I’m truly impressed by how this compact device holds its own against larger pumps,” writes Holly Crocker, an exclusive pumping mom of two and What to Expect contributor. She also finds it more comfortable than other wearable pumps, thanks to the unique double-sealed flange. “It acts as a cushion between your breast and the collection cup, preventing that annoying pinching sensation.”

The S12 Pro features three modes — stimulation, expression, and a combo massage/pumping mode — plus nine suction levels so you can customize the settings to get your milk flowing. What really sets it apart, though, is how effective it is: According to What to Expect moms, the S12 Pro delivers great output, with suction levels of up to 270 mmHg.

Another bonus? Each cup can hold up to 6 ounces of milk — more than most wearable pumps. Holly found this especially helpful since she has an oversupply.

One downside: It's not the most discreet option. With the motor sitting on top of the cup and a somewhat loud volume, the S12 Pro probably isn’t your best bet for pumping on the go. But if you're pumping at home and want to avoid being tethered to the wall, this is a strong choice.

Tested by Holly Crocker, mom of two and What to Expect contributor: 

"My output is just as good, if not better, with the Momcozy S12 compared to the electric breast pumps I’ve used in the past — those with bulky motors and hard-to-clean tubes.

Another favorite among What to Expect moms, the Elvie Stride earns rave reviews for its ease of use and efficiency. But the real standout element is its power. While most wearable breast pumps have the motor on top of the collection cups, the Elvie Stride's is separate (it’s connected to the cups by tubing), giving the suction some serious power: It goes up to 300 mmHg, delivering on-the-go hospital-grade strength.

This level of power has remained in the brand’s latest iteration, the Elvie Stride 2. The biggest enhancement is in the fit, namely the six nipple options (including a sizing tool) and material (a soft silicone versus stiffer plastic), which help the cups contour to the breasts for improved comfort. And don’t worry, it still boasts the same noise-reduction technology that improves moms' ability to be on the go. 

"Despite its power, the Elvie Stride is blissfully quiet, so you can wear it while working and not draw attention to yourself," Jaclyn King, a mom of two, writes in her review of the Elvie Stride. Jaclyn also notes the Elvie Stride is incredibly portable and compact, despite the tubes. This, however, makes it less discreet, but you can clip the motor to your waistband or tuck it in your pocket, which many moms say makes it possible to wear the pump while doing other things.

Like all Elvie pumps, it connects to an app, which allows you to control the pump remotely, adjust the intensity settings (10 choices with stimulation and expression modes for natural suction), and check your pumping history. (You don’t have live milk monitoring with the Stride; however, the silicone cups make it far easier to see the amount manually.) 

Tested by Jaclyn King, mom of two and What to Expect contributor: 

"The Elvie Stride has several features, like a powerful motor and decent cup capacity, that make it ideal for moms who want the convenience of a wearable pump but the power and price of an electric pump." 

When looking for a discreet breast pump, noise level is an important consideration — and this wearable pump seriously delivers in this department, emitting just the faintest sound while it works. I used the Elvie while breastfeeding both of my sons and found that the motor was quiet enough to use during Zoom calls.

In addition to its gentle sound, I found this pump to be generally excellent: It’s intuitive, easy to set up, sleek and incredibly discreet. It was small and lightweight enough for me to wear in my bra for an entirely hands-free experience. At 5 x 4.3 x 2.7 inches, it’s one of the slimmest wearable pumps on the market, making it one of the best wearable breast pumps for moms who are prioritizing portability. 

Jaclyn also used the Elvie throughout her breastfeeding journey, and found it to be a much more discreet pump overall. "The slim profile and lack of tubes or separate motors make it easy to wear anywhere," she writes in her review of the Elvie Pump. "It’s not completely invisible, but is very discreet."

As a bonus, I also found the Elvie app to be impressive (as do many other What to Expect moms). I could watch how much milk I’d pumped in real time, as well as review information about my pumping history. 

One downside, however, is that the parts are smaller. I found them somewhat tricky to keep track of and clean compared to other wearable pumps on this list. The cups are also a little difficult to pour milk out of, and they’d occasionally overflow and leak if I wasn’t paying close attention while pumping (though I had oversupply, which may be why I had this issue).

Tested by Sarah Darby, mom of two and What to Expect's Senior SEO Strategist:

"The Elvie definitely fulfills its role as a wearable pump because it is super quiet, fits easily inside a nursing or other stretchy bra and I found it relatively easy to clean."

Medela makes one of the best electric breast pumps, and their Medela Freestyle Hands-Free Breast Pump is a newer-to-the-market model that’s quickly become a top choice among What to Expect moms. Very similar to the popular Medela Freestyle Flex (which has a design that’s similar to the Baby Buddha), this newer version from the same company has wearable collection cups to make it truly hands-free.

One of the Medela Freestyle’s most compelling features is how incredibly lightweight it is. Weighing less than 1 pound, this is the lightest wearable breast pump on our list, and many moms appreciate that this puts less pressure on your back and makes the pump even more wearable and portable. Another plus: There are only three parts to clean, fewer than most competitors, and the pump works with Medela’s PersonalFit Flex parts too, which is helpful if you already have them from using one of the brand’s other products.

Medela has a handy Family app that lets you track your pumping sessions and milk output. And with a suction power of 245 mmHg, it isn’t the strongest wearable breast pump but is above average.

This pump does have tubing, which some moms may dislike because it means the pump is a little less discreet when out and about. But the Freestyle remains an excellent option, especially if you already use Medela’s other pumps or bottles and can keep everything compatible.

Unlike the other models on this list, the Willow 360 allows you to move in any position — even bend over — while you’re pumping without worrying about leaks. A huge plus if you're out to dinner or a movie and need to express.. 

How? It collects milk into clever “O”-shaped leak-proof milk bags rather than a built-in storage container, allowing for 360-degree mobility. 

"The standout feature of the Willow 360 is the total freedom it offers while pumping. I can keep up with my toddlers, do chores, and even lie down without disrupting the pumping process," Christine Benton, a mom of three, writes in her review of the Willow 360. 

Although it's pricier than many other wireless pumps on the market, it has a good battery life (one charge gets you five 15-minute pumping sessions), connects to an app and doesn’t require much work on your end. The Willow has two phases, stimulation and expression, and automatically switches gears when it senses a let-down — which means even less effort on your part. Plus, there are only two parts to clean (far fewer than standard breast pumps), which you can wash by hand or pop in the top rack of your dishwasher.

The major downside to the Willow 360, however, is that each bag has a smaller capacity than most other wearable pumps (just 4 ounces per side). You also need to continuously replace the bags, which are sold separately, so over time will add to the cost of this already-expensive pump.

"The convenience and comfort of the Willow 360 have made it easier to stick to my exclusive pumping goals." 

The original BabyBuddha Breast Pump went viral for being a compact powerhouse. And the BabyBuddha 2.0 follows suit. With an impressive suction power of 315 mmHg, it's comparable to electric pumps, which lactation consultants say are preferred for increasing and maintaining milk supply. Some moms say the BabyBuddha 2.0 even cut their pumping times in half compared to other pumps on this list. 

However, that power can be a bit much, especially for new moms. So, the brand improved upon its stimulation and expression modes, offering a higher level of customization. There are now 21 comfort settings (nine new choices, including a softer stimulation mode). Plus, the intensity of the “long pull” stimulation, while still effective, was lowered by 20%. 

As is, it’s not the most discreet nor is it truly wireless; it requires a lanyard to carry the motor, which is about the size of a cellphone and less than a pound. If, however, you buy the compatible BabyBuddha Hands-Free Collection Cups ($65), then it's far easier to hide this power pump. (Not to mention the cups hold up to 8 oz. each!) 

It also comes with multiple flange sizes — 22mm to 24mm — and lactation consultant Paula Norcott stresses finding the right size is crucial to maximizing milk flow. 

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." There are seven temperature settings to toggle between, from 95 to 105 degrees Fahrenheit, to help stimulate milk flow. The best part? You can heat them up beforehand, thanks to the brand's handy smart app. Not surprisingly, she’s been using it in every possible scenario since: at home, in the car, at social events (including two weddings!) and during middle-of-the-night feeds. 

“Since I both breastfeed and bottle-feed, my baby often only had the stamina to nurse from one side before falling asleep. Instead of sitting up longer to pump the other breast manually, I’d pop the Eufy on the opposite side while she nursed,” Buxton shares. “It saved me time, helped maintain my supply, and made those exhausting night feeds just a little bit easier.”

It’s also incredibly quiet (operating at just 46 dB — about the same level of noise as a desk fan), has an incredibly long battery life (up to five days of power with the magnetic charging case, based on three 20-minute sessions) and is discreet, providing the flexibility of being able to wear it anywhere. 

Her only complaint is all of the “small, tricky parts,” which, if not assembled correctly, reduces the suction power significantly. Cleaning isn’t exactly easy, but not necessarily tedious, either. It also ships with a brush, storage bag and dust covers. And while it doesn't replace a manual pump in terms of power (though it does reach an impressive 300 mmHG), the HeatFlow technology alone makes it a splurge-worthy wearable. 

Tested by Liz Buxton, mom of one and What to Expect’s Shopping Content Director:

“I could pump while wearing my normal clothes instead of feeling like I had to suit up just to extract some milk,” she says. “I wore it on car rides with company present, and while it does make some noise, it wasn’t loud enough to be embarrassing or disruptive."
