High quality for a low price!
I chose this product because it was the most cost effective for me. I bought this to store milk overnight and then I’d pour into a bottle & warm it by the bed. This kept me from having to go to the kitchen and prepare bottles in the middle of the night. Easy to clean, not bulky at all. Keeps milk extremely cold for an extended period. The color is pretty! I ordered the pink cooler. This has also been convenient for outings because it’s slim and fits nicely in my diaper bag. Would highly recommend this product!!

Great for working moms on the go!
This saved me through out my pumping journey! I regret not buying this with my first. Fit perfectly in my pump bag and kept my milk cold throughout the whole work day. Easy to clean. I unfortunately dropped mine within the first week of buying it and got some dents on it but it did not affect the function what so ever. Supper happy with my purchase!

Best Newborn/ Pumping Purchase EVER!! Highly Recommend
This is a must have for pumping moms. I wish I got this sooner or added to my registry. This is perfect for pumping when the weather is above 40 degrees and when you are on the go, or are unsure if you’ll be home within that four hour window and need to keep your breast milk cold (or at a safer temperature) until ready to use it. It is also great for storing your milk at work, or while traveling. It is thin enough to fit in cup holders and sides of diaper bags, work bags. It looks subtle, like many popular water bottles these days. It is easy to put together and apart. It cleans easily as well. The ice pack doesn’t take up much room in the freezer either. All pieces fit together snug and well so you don’t have to worry about spillage of milk or air/ other things getting in, and you’re good if it tips over too on accident for that reason. The only thing to consider is if you are a breast milk over producer, keep in mind this size fits up to 16 oz per the product info. If you think you will pump more than that in a single session, or work day, you may want to find a bigger one or bring additional storage measures to keep your milk safe. If you produce 16 oz or less in a day, pump session, or while you’re gone between storing your milk with fridge access, for the price point this is a NO BRAINER! Again, I would recommend it to anyone who fits those parameters, will suggest to others to put on their registries and will be using again with future kids! I am also thinking it can double its use as our little one grows when they’re no longer taking breast milk, as just a general thermos for snacks, juices, water, or other items needing to be kept cold!

Garbage Ice Pack
Wanted to like but this cooler comes with a faulty ice pack. After purchase, my first one cracked open from simply placing in my freezer overnight for use. Being within the 60 day warranty, I was able to get a new one from customer service. That one lasted a bit longer, but also cracked overnight in my freezer in less than 60 days. However, I was not given a new one because they don’t actually guarantee the product for 60 days- they’ll just replace broken parts within 60 days of original purchase date. Of course the ice pack is product specific, so you have no choice but to buy a new one at that point. Especially since the thermos is barely insulated and keeps nothing cool without the ice. For being a product most moms only need for 1 year, they certainly guaranteed sales by designing it so you’d have to buy it at least 3 times. Save your money or find something else.

Thoughtfully designed cooler that makes pumping on the go more convenient
I purchased the Willow Portable Breast Milk Cooler to safely store breast milk while pumping away from home, and it has been a reliable solution for short outings and busy days. I’ve used this cooler after pumping during errands, appointments, and times when I didn’t have immediate access to a refrigerator. It fits Willow milk containers perfectly and keeps milk cold for several hours without needing ice packs or extra prep. I like that it’s truly grab-and-go — there’s nothing to freeze ahead of time, which is a huge plus when you’re juggling pumping, schedules, and kids. The cooler itself feels well made and durable. It has a solid, structured design that protects the containers inside, and the lid seals securely so I don’t worry about leaks or temperature loss. It’s also compact enough to fit inside a tote or diaper bag without taking up too much space, which makes it more practical than a traditional bulky cooler. What I like most: • Keeps breast milk cold for several hours • No ice packs required • Designed specifically to fit Willow containers • Compact, sturdy, and easy to transport • Simple to use with no setup Things to consider: • Capacity is limited, so it works best for shorter trips rather than all-day pumping • The price is higher than basic coolers, but you’re paying for the convenience and compatibility Cleaning has been easy so far, and the materials feel like they’ll hold up to regular use. For me, the convenience and peace of mind outweigh the cost, especially when pumping on the go can already feel stressful. Overall, this cooler does exactly what it’s meant to do and has made transporting milk much simpler. I’d recommend it to Willow pump users who want a reliable, hassle-free way to keep milk cold while out running errands, at work, or during short travel days.

Beware of cracks in the ice pack rendering useless. This is old model and parts can’t be replaced.
This was one of the best baby items I got as an exclusive pumper - until the ice pack cracked. Unfortunately there’s no way to use it without that specific ice pack because it is made to be part of the lid. (Which consequently made it super easy to put together and use.) They’ve since revamped this and the new version is a bit more cumbersome, but at least the ice packs could be changed out on the new version. Beware as they will not be able to replace anything on this old version. I used this daily at work and overnight in my room and it keeps milk cold for at least half a day in normal conditions. I haven’t tested it beyond that.

Stays Cold as Needed but Minor Leaks
This cooler works great to keep your breast milk cold. I did have issues with it leaking if it was tipped over. However, as long as it stays upright I have no issues!

Willow Cooler: A Pumping Mom's Dream for Work and Commute
I absolutely love the Willow Portable Breastmilk Cooler! This cooler has solved my biggest pumping challenge: safely transporting milk during a long commute and keeping it cold all day at work. I appreciate that I only need to take one container to work—it simplifies packing so much and completely eliminates the stress of figuring out refrigeration on the go. Not only is it incredibly functional, but it’s also cute! I love the modern, sleek design. I own all three colors and enjoy being able to mix and match the pieces, which adds a fun touch to my pumping gear. It also holds a fantastic amount of milk, which is essential for a full day away from home. The thoughtful design extends to maintenance, too. The pieces that touch the milk are dishwasher safe, making the cleaning process wonderfully easy. When I'm home or near a fridge, I just pop the included ice packs into the freezer so they are ready to go for the next day. This cooler is efficient, stylish, and durable—a true must-have for any pumping mom.
