Gentle Like a Baby’s Mouth
Time to take a fresh look at wearable breast pumps.
The Momcozy M5 features a horizontal pumping angle that mimics your baby’s natural nursing position, not upward or downward pulling that can feel rough or painful.
This angle helps deliver gentler suction, encourages better milk flow, and makes every session more comfortable.
Because wearable should mean more than just hands-free — it should feel natural, too.

Pump Comfortably. Pump Naturally.
Unlike traditional pumps that pull nipples up or down, the Momcozy M5 uses a unique horizontal pumping angle — mimicking the natural position of a baby’s mouth. This baby-inspired design helps reduce discomfort while encouraging more milk flow, making each session more effective and gentle.
Because moms and babies were made for each other — and now, so is your pump.
More Milk. Less Time.
Struggling to fully empty your breasts? You’re not alone — and it’s not your fault. That’s why the Momcozy M5 adds an upgraded Mixed Mode, designed to gently stimulate and loosen milk ducts while expressing. This dual-action pumping helps speed up letdown and supports more complete drainage.
With 3 modes and 9 adjustable suction levels, you can always find the rhythm that works best for your body.
All-in-One Design
Cut the motor and cut down the size — Momcozy M5 is just 8oz, only 2/3 the size of typical breast pumps. It’s the lightest, most discreet choice for moms on the go.
No more tangled wires or being tied to the wall — pump anytime, anywhere, even during a busy work meeting, without drawing any unwanted attention.
Designed to bring you freedom and ease, because we know every moment counts.
Four Mom-Approved Colors
We listened — after half a year of interviews with real moms, we found out what colors you truly love.
Momcozy M5 brings you four fresh colors, including three brand-new shades inspired by moms who want their pump to be more than just a tool — a stylish “mom pride emblem” you’re proud to show off anywhere.
Because pumping should feel good and look good, too.
Be Fashionable, Be Cozy
As the top wearable breast pump brand that truly listens to moms, we designed a hard-shell storage bag to keep your pump safe from bumps and scratches — and looking neat too.
Because caring for you means making every detail cozy and stylish. Start your cozy pumping journey today!
1. Ensure the breast pump and accessories are installed correctly, and the flange fits your breast comfortably and securely during pumping.
2. Select the correct flange size. Momcozy offers sizes 15mm, 17mm, 19mm, 21mm, and 27mm. Check the flange size guide here.
Use the included “nipple measuring tool” to measure your nipple diameter accurately—measure only the nipple, excluding the areola—to find your perfect flange size.
3. Replace silicone breast pump accessories every 3 months or as needed based on wear and suction performance.
4. For best support, use a full coverage bra, stretch fabric bra, nursing buckle bra, or wireless bra during pumping.
Before purchase: We’ve created an exclusive flange size guide to help moms find their perfect fit. Check out the guide on how to measure your flange size here.
After purchase: Use the included “nipple measuring tool” to measure your nipple diameter and select the right flange size based on your measurement.
Please note: Your breast size can change before and after pumping, so for the most accurate fit, measure your nipple size right before you start pumping to ensure the flange size is appropriate.
All Momcozy pump parts that come into contact with breast milk are BPA-free, ensuring safety for both you and your baby.
To maintain optimal pump performance, some accessories need regular replacement. If you notice a decrease in suction, check your parts—especially the valves—for signs of wear, fraying, or stretching, and replace them as needed.
Diaphragms, duckbill valves, and inserts are recommended to be replaced every 2–3 months.
Flange shields and milk collectors should be replaced every 6 months.
Absolutely! A portable breast pump is a smart choice for busy moms who need convenience and flexibility. It lets you pump anytime, anywhere—whether at work, running errands, or traveling—without hassle. Although the upfront cost might be a bit higher than traditional pumps, the time saved and the freedom gained make it well worth it.
For example, the Momcozy M5 is a favorite among moms who want a reliable, easy-to-carry pump. Its compact all-in-one design, long-lasting rechargeable battery, and quiet operation make pumping on the go comfortable and discreet.
Yes, most health insurance plans in the U.S. cover breast pumps, including portable and wearable models. Thanks to the Affordable Care Act (ACA), many insurance providers must cover breastfeeding supplies at little or no cost to you.
To find out exactly what your plan covers, it’s best to check directly with your insurance provider. Momcozy also works with top DME partners to help you get your pump covered smoothly and easily.
Most moms find it helpful to start using a portable breast pump a few weeks before going back to work or traveling. This gives you time to get comfortable with the pump and build up a good milk supply.
If you have concerns like low milk supply or simply want the flexibility to pump anytime, a portable pump is a great choice.
Remember, every mom and baby is different — trust your body and choose what feels right for you both.
