Pros & Cons

  • The USB battery charger allows recharging using a laptop, powerbank, or car USB charger
  • All pump parts (except the pump motor) are dishwasher-safe and sterilizable.

  • Some moms complain that the pump’s suction is too strong and painful, even at the lowest settings.
  • Even if it’s portable, the pump has a bulky top for the motor and controls, which can be a challenge for discreet pumping in public.

  • Plenty of parts (around seven pieces per pump) to clean.

Positive Reviews 

This is my 3rd wearable pump. I should have start here. Busy moms and working moms this is the original pump all the others are copies. THE PARTS, are made differently to stay intact and in place. The suction is powerful enough I use it on 5 and it hurts. Get you a smaller flange and you are good to go !! . And when it’s sealed , NO LEAKS, you won’t need an extra shirt. WORTH EVERY PENNY!!!” – Reviewer on Amazon.

This is my second set of momcozy pumps and both sets have died within less than a month. First time I thought it was a coincidence or the fact it was an older model. But these cracked within a week.” – Reviewer on Amazon.

Positive Reviews

I can get so much done around the house AND take care of my baby, all while pumping away. It’s so quiet and gives me 360° mobility.” – Reviewer on Target.

Negative Reviews

I have purchased all three flange sizes as well as purchased silicone inserts to try and find the correct size to soften the experience for myself, and no matter what I’ve tried, the Willow hurts my nipples and/or doesn’t empty my breasts.” – Reviewer on Target.

  • It has adjustable suction levels.
  • It’s wearable and connects to an app on your phone.

  • It can be used with three flange sizes (21 mm, 24 mm, and 28 mm), with two already included in the box.

  • It’s dishwasher-safe.
  • You can use your FSA/HSA debit card to buy this breast pump.

  • It’s an expensive pump. The cost of just one hub is still more expensive than popular but non-wearable hospital-grade breast pumps such as the Spectra S2.
  • It’s usually considered an upgrade by insurance companies. So, you can’t get it for free through insurance, but your policy might still partially cover the costs.
  • If you only buy one hub, you’ll need to wait at least 60 minutes before you can use it on your second breast.
  • You can buy two hubs/pumps for less hassle, but that makes the entire system more expensive.
  • You can’t use this while charging because of the automatic shut-off safety feature.
  • You can only pump directly into the milk bottle, not with milk bags.
  • Lights on the pump can be visible beneath your clothes.

Positive Reviews

Okay, so I LOVE these for the convenience factor. When I have a meeting or need to be on the road for work, these are a lifesaver (so I do not have to miss 30 minutes to go pump).” – Reviewer on Amazon.

Negative Reviews

These stupid things will stop working for no reason and shortly after purchase, even after updating the firmware and checking the charging cords, etc. Contact the company, and they will ship you a new one. I had to replace BOTH of mine during the first month. I hate them.” – Reviewer on Amazon.

What Customers Say

Positive Reviews

I typically pumped 25-30 min with my Spectras, and I do at least 30-40 min with the Freemie. I got about 1-1.5 oz less than with my Spectra. It’s worth noting that the timer counts down (not up) and high suction with low speed helped me get the most out.” – Reviewer on Amazon.

Negative Reviews

The suction was so little that I got one drop out of milk after 20 minutes. I’m returning it.” – Reviewer on Amazon.

What Customers Say

Positive Reviews

I love this breast pump! I wanted a wireless Breast Pump, but I wasn’t willing to pay $500.00 for it. It has done me well so far. It does the job, and I am satisfied.” – Reviewer on Amazon.

Negative Reviews

The suction on these is SO intense it just hurts my nipples. I can only turn it to the 2nd setting before feeling like it’s going to rip my nipples off. It would be one thing if the suction made me produce more milk, but with these, I’m lucky to get an ounce in 30 MINUTES, a waste of time and money.” – Reviewer on Amazon.

Best Wearable Breast Pump FAQs

Can You Use Standard Double Electric Breast Pumps As Wearable Pumps?

Regular double electric pumps such as the Medela Pump in Style and the portable Medela Freestyle Flex can be used as hands-free pumps but not as wearable pumps.


What’s The Difference Between Wearable Vs. Hands-Free Breast Pumps?

Some moms might be confused about the difference between wearable and hands-free pumps.

All wearable pumps are hands-free, but not all hands-free pumps are wearable.

The true wearable breast pump is something that can be worn discreetly inside your clothes, without others noticing that you’re pumping even if you’re in a public place.

Many hands-free breast pumps are used along with pumping bras but are not discreet or wearable. The milk bottles could stick out from the hands-free pumping bra unless you wear milk collection cups.


Are Wearable Pumps Easy to Use?

Unlike traditional breast pumps, you might need more time to get used to wearable pumps. Some moms report difficulty in latching, especially if they haven’t established lactation yet.

Though some moms report leaks during the first few times of use, they improved latching and pumping in the next sessions.


Will My Insurance Cover Wearable Pumps?

Most insurance policies won’t cover wearable pumps because they are considered upgrades.

But it’s best to contact your insurance company to ask how much they’re covering or if they’ll cover the cheaper wearable pumps listed above.


What Accessories Do I Need For Wearable Breast Pumping?

Unlike traditional pumps, you won’t need a lot of accessories for your wearable pump. But you’ll need the following:

  • Nursing bra
  • Soft brush for cleaning
  • Drying rack
  • Replacement parts

Are Wearable Breast Pumps Good?


  • The pump doesn’t need to be plugged with an AC adapter to the wall, so you don’t have to stay in just one spot during the pumping session (usually for 10 to 30 minutes).
  • It lets you pump even if you’re busy doing other tasks.
  • It can let you pump discreetly in public.
  • It lets you build up your milk supply even if you’re spending time away from your baby.
  • It helps boost your milk supply.
  • Most wearable pumps are designed with a closed system that prevents backflow.
  • The milk flow isn’t hampered because the pump is directly connected to your breast.


  • Most wearable pumps are more expensive than regular breast pumps.
  • Wearable breast pumps are considered upgrades and are typically not covered by most insurance plans. So, you’re likely to pay for the pump unless FSA or HSA funds are accepted.
  • There are lesser pump parts used, but the curved cup design might be harder to clean.
  • The levels of suction might be limited compared to standard breast pumps.
  • Some moms find it difficult to latch with the wearable hands-free pump. This could lead to leaks or decreased amount of milk collected.
  • The cups aren’t always spill-proof. So you’ll still need to stay in one position while pumping so that you won’t spill the milk.
  • Most of the pumps won’t work when charging. So, you’ll have to make sure they’re properly charged before the pumping session.

Tips When Using A Wearable Pump

  • Keep the breast pumps charged so you won’t need backup if the pump loses power in the middle of a pumping session.
  • Wash your pump parts right after each use. Cleaning the parts can be difficult if milk hardens in some sections.
  • It’s a good idea to buy an extra charger.
  • Use the correct flange size for better latching and suction.

Summary & Recommendation

So, have you chosen the best breast pump from the wearable pumps we reviewed above?

Here’s a guide to help you choose:

Which Wearable Breast Pump Is Best?

Expensive But Discreet Pumps

If you’re willing to pay at least $279.99 for a single pump or up to $499.99 for a double pump, then you should choose from these quiet pumps with a discreet design:

Is Willow Or Elvie Better?

The Willow Pump is the most discreet of these three, but it only has a 4oz collection cup.

We rated the Elvie Pump as the best bag-free wearable pump in a previous review, but the lights on the pump make it less discreet than the other pumps.

The Freemie pump is the cheapest of the three and has 8oz cups, but it only has one-hour battery life.

Cheaper But Not-So-Discreet Pumps

These pumps cost just around $100 for a pair, but their designs aren’t as discreet as the more expensive pumps above. They can also be loud and may not be ideal for pumping in public places.

But if you just want to have cheap, wearable pumps you can use at home, then you can choose from these pumps:

  • Momcozy

Are Hands-Free Breast Pumps Worth It?

Some hands-free breast pumps can be several times more costly than traditional pumps but can be quite handy if you want to pump discreetly while in public or on the go.
