Willow® Portable Breast Milk Cooler

$59.99

Store up to 16 oz of milk at a safe temperature for up to 24 hours (no ice cubes necessary!) with our new patent-pending Portable Breast Milk Cooler. Read more about milk temperature and our safety testing.


Featuring a gel ice pack that remains separate from milk (and is TSA compliant!), and a top loop for easy carrying, it's the insulated breast milk cooler you'll bring everywhere. It also fits in most car cup holders!


P.S. Already have our Pump Anywhere Bag? Our breast milk chiller was designed to fit seamlessly in the bag's bottom and top sections, so you can carry less and do more! (Even better: it also fits in most cupholders!)


Key features:

  • Fits up to 16 oz of breast milk (that's an average of 3-4 pumping sessions!)
  • Insulated bottle keeps breast milk at a safe temp for up to 24 hours with built-in gel ice pack
  • Leak-proof design for spill-free storage of liquid gold
  • Easy to clean (with just two milk-contacting parts) and dishwasher-safe

    Amazing!

    Our family is out and about a lot and this product is a lifesaver. We use the Kiinde twist pouches when I pump with my Willow GO and just shove the pouch inside this bottle instead of pouring the milk in directly. This has helped us keep it clean while away from home. Highly recommend this if you plan to travel!

    So much easier

    Prior I had been using bags and a soft cooler bag which was okay most days but when I had to be on the go all day my ice packs leaked water through the cooler and I didn’t zip a bag and lost a ton of milk. This takes up less room in my bag, mess free while out all day and I loved that it combines my milk as my sessions can be very different in composition throughout the day. Plus I love that I don’t need all the disposable bags!

    If you are on the fence this is a serious upgrade from the bags and cooler situation!

    Nice, cold, and easy to use

    This makes it so easy and discreet to carry your milk! It stayed cool all day long while I was out! My only complaint is I wish it held more!

    Love!

    It’s perfect! Holds a lot and less bulky than a cooler/ lunch bag with ice packs.

    Great for travel and when working and don't have access to a fridge.
