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).

Only downfall is I am more productive

I felt like pumping was restricting me to a little seat in the living room, near an outlet, alone and bored. Now I am free to roam.working from home and having my baby at home with me while I work always made me nervous to start pumping for fear I'd be interrupted by a baby cry that I couldn't tend to because I was attached! The willow has made me so productive, I can take care of household chores, soothe baby in bed, attend meetings and calls all while pumping! Only downfall is my excuse to "do nothing" while pumping is no longer valid 😂 I am now ultra productive!

Proud Pumping Mama!

Where do I start with my Willow pump!? It’s been a game changer, LIFE CHANGING! With my first son, I was horrible at sitting still for more then a few minutes to be able to pump. When I came across the Willow with baby #2, I was hesitant because of the price tag, BUT I hit the order button and I have ZERO regrets! My pump is my best friend, goes with me everywhere and I never thought I’d love pumping so much and it’s all because of my Willow pump! Being a mom of a 3 year old and a baby who’s approaching 5 months, home life is BUSY, but nothing I can’t handle knowing I can keep going while still pumping. Being able to toss them in the diaper bag and head out for the day is wonderful! No more rushing around to get back home to pump. I’ve pumped while car shopping, at the beach, vacation, getting my hair done, you name it! The reusable containers are awesome, but I LOVE the spill proof bags when I’m on the go and being able to toss them in a cooler until I get home. The Willow is worth EVERY penny. Going on 5 months strong with my Willow and so proud of it!

Great pump, wonderful customer service

I initially had problems pumping with Willow, due to being a FTM and all. I reached out to customer service and they scheduled me for a coaching with Jamie M. She was amazing. As you might know the process to pump is intimate (stimulate nipple, open boobs etc) especially in front of a stranger. Jamie put me at ease with her personality and even better she showed me tips on how to get the most of out my sessions and ensure my pumping experience is pain free.

Now I am a happy Willow mama
