10 Best Breast Milk Coolers of 2024

The Babeyer breast milk cooler is a sturdy option for those who plan to breastfeed for an extended period. Users have found it stands up to plenty of journeys either to and from work or between home and daycare. There are none of the zipper issues that seem to develop with other options.

A clip on the handle makes it easy to attach to your stroller or another bag, and the leather sheath on the handle ensures carrying by hand stays comfortable. Meanwhile, both the inner and outer surfaces are easy to wipe clean, and the leather bottom provides additional stability.

It was challenging to find anything wrong with this cooler, and the only thing we could complain about was the rear pocket. The makers promote the usefulness of the pocket, but it is pretty small and isn’t secure.

The Chiller by Ceres Chill has an adapter, so you can use it with most brands of pumps. You simply attach your equipment to the canister and pump directly into the cooler. This unique style is basically one metal canister inside another, and you can use it to store milk in three ways.

First, you can put ice water in the outer canister and pump directly into the inner canister. This allows you to pump and store a maximum of 12 ounces for 20 hours or more without additional refrigeration.

The second configuration allows you to put ice water in the inner canister, which sits inside the outer bottle. You then pump directly into the outer bottle, and this will enable you to store a maximum of 24 ounces for up to 20 hours without additional refrigeration.

Finally, you can use the outer canister alone. This configuration will hold up to 34 ounces, which can be decanted into bottles, and requires additional refrigeration.

The chiller lid doubles as a bottle.

The Cold Gold breast milk cooler is made to coordinate with the Sarah Wells breast pump bag and the Pumparoo wet and dry bag for your used breast milk parts. Cooler bags can be matched with bags of the same color and pattern or coordinated with breast pump bags in a solid color.

With a rounded, stretched cube-type shape, the cooler itself is a relatively basic design. The handle on top of the bag is sturdy, with double O rings and a clip that opens, allowing you to attach it to and detach it from other items with ease.

The lining can be wiped clean using a damp cloth with hot soapy water, and the outer fabric can be cleaned in the same way.

This freezable breast milk cooler from PackIt does not require any ice packs. Instead, the walls of this cooler are infused with a freezable gel. You place the entire cooler into the freezer for twelve hours, and it is then ready to use.

The main compartment is divided in two, with a central wall. The wall is also infused with freezing gel, acting as an ice pack in the bag’s center.

There is a small clear pocket on the front of the cooler so you can insert a name tag, and there are six different designs from which to choose. The advertised capacity is four 5 ounces bottles, and users say there is plenty of room for these, plus one or two small feeding accessories.

If you need plenty of room for large bottles or smaller bottles with additional ice packs, the JAX 2020 is a good option.

We found you could fit six full-size bottles in the cooler, with the only issue being that with some brands of wide bottles, you had to use a small thin ice pack. Tall bottles were no issue, no matter their capacity, and we like that you can fit them in the cooler when they have the nipple and cap attached.

We also like the pouch strap” that’s on the inside of the lid. The strap undoes at one end, and you thread it through the hole at the top of your breast milk pouches and clip the strap back in place. This keeps full bags upright and prevents leaks.

If you need to carry six bottles regularly, the Lekebaby cooler might be the breast milk cooler for you.

This roomy yet compact bag has space for six full-size 8-ounce bottles and the contoured ice pack included with the cooler. The ice pack is shaped to maximize the space between the bottles, helping it to keep your breast milk well chilled for a full eight hours.

The contoured ice pack arrives unfilled, but all you have to do is fill it with water and seal it. This only needs to be done once; there is no need for ongoing emptying and refilling of the ice pack.

We particularly like the inner-bag feature. This bag within a bag just sits there until you have a pill. Then you can remove the inner bag for easy cleaning while your cooler remains unsullied by your breast milk.

Momcozy has an all-in-one lunch bag breast milk cooler, and we must admit we’re a little conflicted about it.

We love that you can store up to six bottles and your lunch or snacks all in one bag. A removable panel separates the two sections, so you can also use the cooler as a larger bag. This makes it versatile enough to use on weekends, for picnics, and any other time you might need a mid-sized cooler.

However, if you’re looking for a bag to drop off at daycare, the upper section is unnecessarily bulky. Plus, at daycare or if you’re taking it to work, it feels like you’re taking up a lot of refrigerator room.

The Medela is an excellent option if you don’t use a breast milk cooler on a day-to-day basis but need one for occasional travel. Small, lightweight, and easy to fit into a larger bag, this option also takes up little space when not in use.

Medela says that if you use it with the ice pack, previously chilled milk will stay cold for eight hours. With freshly pumped, body temperature milk, the chill period is closer to eight hours as well.

However, the CDC says you can carry freshly expressed breast milk for up to 24 hours in a cooler with an ice pack ⁽¹⁾.

This cooler will do the job if you are taking a flight and want the option of feeding with a bottle while in the airport or on the plane.

The MaxiCool cooler can hold four tall, 9-ounce full-size bottles, three wide-bodied bottles, or up to six short 4-ounce bottles. Bottles are kept cool with an ice pack, which is included, and the slim profile means it fits easily into most diaper bags.

A handy front pocket is a useful spot for smaller items such as a baby bib, spoon, or burp cloth. The interior lining is heat-sealed, making it especially easy to clean should there be a leak from your bottle.

J.L. Childress also manufactures a line of coordinating items such as a full-size, full-body changing pad and smaller coolers that hold two tall bottles. Another item that is available is a five-piece diaper bag organizer set that includes a wet and dry bag, a snack pouch, and a mesh soiled item bag.

Inside the U.S.-made FlexiFreeze breast milk cooler, there are 16 pouches filled with purified water. You pop the cooler into the freezer, and the pockets freeze, acting as a built-in ice pack. However, this also means you have to remember to plan ahead and freeze the cooler.

The pocketbook breast milk cooler is ideal for short journeys, transporting a small amount of milk, and for keeping a couple of pouches cold in your bag during a day out. However, the only bottles that will fit in the bag are the mini feeding bottles you see in hospitals.

Consequently, this is not the cooler for you if you need to regularly take milk back and forth between work and home or home and daycare.
