I’ve tried a few different ways to store milk, and the Willow Go cooler has been a lifesaver. If you’re like me, you’ve probably ended up carrying a bulky cooler bag with ice packs at some point, which is not very convenient.
First, the design is honestly beautiful 😍 I have the Juniper color, and it looks more like a sleek insulated water bottle than breast milk storage. I’ve carried it around and no one would ever know what it is. It also fits easily in cup holders and bags. The 25 oz…

Breast milk cooler
I am VERY satisfied with this breast milk cooler. It makes working and pumping so easy and I don’t have to worry about taking a cooler with me or bottles. This is such a great thing to have for breastfeeding moms on the go.

Great built in ice pack; holds a lot!
Really happy with this cooler! The built-in ice pack is super convenient and keeps my milk cold for hours. It’s also bigger than I expected and holds plenty without being bulky. Makes transporting milk so much easier. Definitely recommend!

I love the new added
I love the new added features to the milk cooler: the duo ways to chill and the way the lid comes off to pour your milk into the bottle is perfection. The only thing that I dont love about the new cooler, is the size; it is a bit awkward to handle and store easily in a bag on the go.

Willow new chiller
I love this new chiller. It's my new favorite! Previously I really liked the Boon because I could pour milk on the inside container and not have to pull out the center and drip milk everywhere but THIS ONE is way better. Super simple, take off one cap and pour in, it easily pours out to, all without having to remove the center ice pack container piece. I have used boon, the older willow, momcozy, and off brands. Occasionally the middle piece will slightly inscrew when I unscrew the top cap but…

New & Improved
I love this cooler! It’s honestly been my go to for overnights compared to their competitors. I will say the inner lid where you pour the milk can get loose so make sure to tighten before pouring just in case! Making it super easy to chill breastmilk has been amazing - love that the cooler part never touches breastmilk making it easy to throw in freezer for later use. Also most bag pocket & cup holder compatible 10/10

Milk Cooler
I really like the new willow milk cooler. It feels like a new and improved version of other coolers on the market. I really like that you can use an ice pack or fill the container with ice to keep the milk cool. I’ve always preferred the ice packs and love the idea that I can refill with ice if the pack starts to melt or if I forgot to freeze the pack. I love this size as well, it fits right into my backpack for work. I would love for a smaller version as well that I can use on to go when I only…

Very Convenient!
Loved this milk cooler so much. I especially loved how it was small enough to fit in the side pockets of my diaper bag as well as car cupholders! It kept my milk cold for several long day trips where I had no access to a fridge.
