Milk Storage Options

Pump Your Way

Willow is the only in-bra pump that gives you the flexibility to pump directly into spill-proof storage bags (24 included with Pump Kit) or reusable Containers (sold separately).

  • Everything works inside the pump and inside your bra, with no external tubes, cords or dangling bottles to hold you back.
  • Milk flows into the spill-proof disposable collection and storage bag or reusable container inside the pump (container accessory sold separately).
  • Smart, proprietary technology responds to your body and maintains suction similar to a baby, enabling true mobility without spilling a drop.
  • Lie down, bend over, play with baby, take a conference call… pump wherever the day takes you!
  • Re-engineered from the inside out. Our smart, wearable breast pump offers more comfort and control – and helps you get more milk.
  • Spill-proof in any position. Willow is the only breast pump that’s totally enclosed and spill-proof in any position with self-sealing milk bags.
  • Smart Suction Technology adjusts based on your preferences to increase output (no need to press a button).
  • Seven levels of suction. Willow is comparable to most traditional double electric and hospital grade pumps, with two lower suction levels and a sensitivity setting.
  • Quiet pumping. Pump wherever the day takes you— with no disruptions.
  • In-bra pumping. No need to undress or buy new bras—your regular maternity or nursing bra is perfect for Willow!
  • App Connected. Our wearable pump connects to our app with step-by-step onboarding and simple, fast pairing–plus volume tracking, session history and pumping pro tips. Compatible with iOS (iPhone 6 or newer) and Android (supported models).
  • Easy to wash. Only two parts to clean and it’s dishwasher safe.
  • BPA free.
  • Rechargeable battery lasts up to 5 pumping sessions to get you through the day.

Compatible with our new app exclusively for Generation 3, which offers fast, easy pairing and step-by-step onboarding.

Freedom to pump!

The Willow is life changing, if I could gift one to every new mother, I would. I never tried another pump, the Willow was actually offered through my employer. I realized early on that feeding/pumping takes a ton of time and I didn’t realize sometimes I’d be stuck and NEED to pump. I’ve successfully pumped in my car, pumped on a plane, pumped when and where I need to. I truly believe the freedom to move around while pumping has made a huge difference in my postpartum recovery. It’s important to note that sizing really matters. I had 24 and then 27mm flanges. After some issues, I realized I’m actually 17mm. Your nipple size may change a few times! Thank you Willow!

The freedom

This is freedom I wish I had these pumps with my first round of breastfeeding, but now that I'm a mom of two I appreciate it so much more!!! I'm not stuck to a pump for sessions instead I can be making lunch, playing or on the go with the babies ♡ every mom thinking about making this investment really should, it makes your breastfeeding journey so much easier!

Willow Pump/ Container Accesories

This pump has saved my life at work! I don’t know how I could have went back to work as a hygienist without this. It’s very discreet and quiet, you just might appear a little busty! 😉

Slow start but it works!

Took a while to adjust (a month) but now I am hands free and doing all the things I need to while pumping. Also- this thing empties me (8oz) in less than 5 min when I’m full. Love love love.

Love!

Once I got correctly sized it was a complete game changer for this pump. Having 2 littles under 2 I am SO busy that it is amazing not being stuck to a wall all the time. Wouldn’t ever go back to another pump!
