Best Wearable Breast Pumps of 2025, According to Experts and Parents

The Go was the second pump released by Willow, an innovator in the world of wearable breast pumps. (Their Willow 360 is their original pump that started it all.) And while it lacks a few features compared to the 360, it more than makes up for them in functionality, ease of use and value—and it’s the best-performing wearable I’ve ever used.

Convenience and performance are two of the best things about the Go, both in my opinion and according to many parents we polled in our Best Baby Products survey. “[The Willow Go] absolutely made my pumping journey so much easier and has made it so that we are still going strong,” one parent told us. “Game changer” is another popular user comment. That’s because while the Go may not perform quite as well for some pumpers as a traditional pump like the Spectra might (you can read more about the whys behind that below), it makes the often arduous task of pumping so much easier—and that’s a really big deal. The Go is compact enough to toss into a small tote and be on your way. While it’s not completely discreet, it slips into your bra and makes it possible to pump out in public or on a Zoom call without most folks even realizing what’s going on under your shirt.

While there is a learning curve with any wearable, I went from popping the Willow Go out of its box to pumping milk in under 10 minutes or so the first time I used it. Nipple alignment—which I struggled with when using other wearables in the past—was surprisingly easy. (Nipple alignment can be tough with wearables because, unlike when you’re pumping a traditional flange, you can’t see what you’re doing. And it’s important because properly aligned nipples equal a tight seal between you and the pump and ensure good suction for maximum milk output.)

I also appreciate the pump’s numerous and easy-to-operate controls. There are two modes, stimulation (mimicking baby’s quick, short sucks to trigger milk flow, called letdown) and expression (stronger, longer pulls to extract milk), and nine different suction strengths, so you can customize what works best for you. Like many pumpers, I did have to pump longer with the Go than with my primary pump, the Spectra S1, to get the same—or maybe even a bit less—amount of milk. But out of all the wearables I tried, it was by far the most efficient. It was clutch when I needed to pump on a plane, at a work event or in my car. I also liked the reusable storage containers rather than dealing with disposable bags.

If you’re comparing the Go to the 360, know that the main difference is you can’t be quite as mobile—the 360 is leak-proof at any angle, while the Go has 45º of mobility. (This was not a big deal to me, though.) The suction pattern on the two pumps is slightly different, and the 360 has two parts per pump to clean versus the Go’s five. You can check Willow’s comparison chart for a head-to-head matchup of the two pumps.

Lighter, sleeker and quieter than the Willow Go, the Elvie is the most discreet wearable pump on the market. It's a good choice if you’ll frequently be pumping in public or an office setting and hope to do so without most people noticing.

The Elvie is slim and quiet. It comes in at around 32 decibels, the quietest pump on our best-of list. (You can watch a cool video comparing the decibel level of the Elvie to that of other breast pumps, but keep in mind that they picked some of the louder pumps on the market.) If you’re using it in a space with even a minimum amount of noise, like hushed talking or the sounds of a quiet office, it’s barely audible, a feature many pumpers appreciate. “It’s very discreet and makes little sound…so you’re not confined in a room for 15-20 minutes at a stretch multiple times a day,” one pumper shared in the Best Baby Products survey.

Like other high-end wearables, the Elvie has a multitude of settings (stimulation and expression mode + seven suction strengths) for comfort and output efficiency and uses reusable bottles instead of disposable bags. You don’t have to toggle manually between stimulation and expression mode with the Elvie—the pump detects your letdown and does it for you, a feature I really like. There’s also an app that helps you track milk volume and pump history, although many pumpers report the volume-tracking feature isn’t accurate and the connection can be spotty. The milk tracking bug can get frustrating since it’s not as easy to look down to check your milk volume as you would with a traditional pump.

There are five parts to clean for each pump, which is on the higher side but not far off from many more traditional pumps. Users also report the pump can be finicky and lose suction if all the pieces aren’t completely dry or perfectly aligned. And while you can move around fairly well while pumping, you need to stay upright; the pump will leak if you bend over.

Until a few years ago, a wearable breast pump would cost you a minimum of $300-400. That’s beginning to change, and the M5 is the best option of these lower-priced wearables. It’s a good choice if you don’t have a huge budget or aren’t sure how often you’ll use or how you’ll respond to a wearable pump.

Like all wearables, pumpers rave about the freedom the M5 provides. “I hated being connected to a wall and loved the mobility,” one pumping parent told us, while another said the M5 allowed her to “leave the house and be out and about,” and without it she “wouldn’t be able to dedicate [herself] to exclusively pumping” for her baby.

Unlike some of Momcozy's wearables where the motor sits on the top exterior portion of the cups, the M5's motors are built right into each pump. (You'll pay slightly more for this feature, but it helps make pumping more discreet.) I like the clear cups for visibility—it's easier to see how much milk you've collected than with some other wearables—and the angle of the flange mimics baby's sucking angle. And speaking of flanges, the M5 comes with three different sizes of flange inserts so you can find a custom fit without having to order anything separately.

If you’re comparing the M5 to other more expensive wearables, know that it holds slightly less milk and is more prone to leaks. Some pumpers also report that the pump stops working properly (the most common complaints are that one of the motors starts to lose suction and that the battery is inconsistent), but that isn’t the case for all users.

A portable pump is a cross between a traditional pump and a wearable. It’s hands-free, but not cord-free—you’ll still need to run tubing from the pump to your flanges. But the motors on most portables are strong and the pumps weigh a fraction of most full-size pumps, so they’re exactly what their name implies: portable. And unlike a wearable pump, you can use one as your primary pump without worrying about output issues.

The BabyBuddha weighs just half a pound, so it’s small enough to wear around your neck or slip into your pocket. The tubing is pretty universal. While not officially condoned by the brand, they devote an entire page to component hacks to show you how to pair it with all different flanges, collection cups and bottles—meaning you can find the combo that works best for you.

While this pump is small, it’s extremely mighty. It has stimulation and expression modes with multiple levels. And the motor is strong. At the highest setting, it’s 320mmHg; the Spectra S1’s max is 270mmHg. (An abbreviation for millimeters of mercury, mmHg is a measurement of pressure and the standard unit of measurement for a breast pump’s suction level.) Pumpers consistently note how efficient it makes pumping sessions and how well the pump empties their breasts.

But what some see as a pro, others see as a con—many found the original BabyBuddha too strong, myself included. I loved the pump’s size and portability, but even on the lowest setting found that the pump was simply too uncomfortable for me. This 2.0 version tackles this issue, adding a Soft Stimulation mode with six levels to offer more variety and improved comfort. Other flaws include volume (it’s pretty loud when compared to other similarly sized pumps) and a short battery life.

Paired with a portable breast pump, collection cups can help you make your pumping session more discreet and offer a more affordable alternative to a wearable breast pump. (You can also use collection cups with a full-size pump, like the Spectra, if you find them more comfortable than traditional flanges.)

Legendairy Milk’s cups feature a breast shield made from food-grade silicone, which some pumpers prefer to a plastic flange. The cups hold eight ounces each and are compatible with a variety of popular pumps, including Spectra, Evenflo, Ameda, Medela and Lansinoh. (There's a "compatibility" section on the product page where you see the full list.) They also come with two flange sizes, so you can choose what works for you. I like the finger grips on the sides; they help you keep a tight hold of the cups to prevent spilling when you pour your milk from the built-in spout.

These cups take a bit of practice to assemble, and there are a lot of parts to clean when you’re done. You’ll need to stay mostly upright while pumping with these to prevent spillage. (A slight lean forward is fine, though.) Keep in mind that similar to wearable pumps, many pumpers report they don’t get quite the same output when using collection cups rather than traditional flanges, something you’ll want to consider if you’re an exclusive pumper or pumping more than once or twice a day and hoping to achieve a certain volume of milk output.
