Are you a nursing working mom who needs a way to safely transport her expressed breastmilk from work to home or from home to daycare? Maybe you are a breastfeeding mom who needs a safe way to transport expressed breastmilk while traveling or out and about? 

An insulated breastmilk cooler bag is the best + safest option for transporting the precious liquid gold you worked so hard to pump all day at work back to nurture your little one at home. 

Here is a list of the 25 best cooler bags for breastfeeding moms. Let’s dive in! 

How Long Will My Breastmilk Stay Safe Before I Can Make It Home?

Breastmilk can be left at room temperature for up to 4 hours. If you don’t feed the breastmilk to your baby within those 4 hours it needs to be placed in either a fridge or freezer to remain at a safe temperature. 

Breastmilk can stay safe in the refrigerator for up to 5 days or the freezer for up to 6 months. Your breastmilk will stay safe for up to 24 hours in an insulated breastmilk cooler bag unless otherwise stated on the cooler. 

It’s best to include an ice pack or cooling gel pack in your insulated cooler to ensure that your breastmilk stays at the correct, safe temperature until you make it home.

What To Look for In A Breastmilk Cooler Bag?

The following criteria are important things that I looked for when making my list of top 25 breastmilk cooler bags + what you should look for or consider when out shopping for the best breast milk cooler bag: 

Size

Size is the most important thing to consider when choosing the best cooler bag for breastmilk that will work for you. When considering the size of the bag think of:

  • Will it be used for a short or long time away from home? How long are your shifts at work? How much do you pump in this time?
  • What size bottles do you pump into? Tall or wide bottles need more room. 
  • Do you plan on cleaning your pump parts in between pumping sessions while you are away? If not you need space in your cooler to keep these cool too. 

Durablilty

Finding a cooler that is durable and made well is especially important for working moms who will be using this cooler every single day. A shoulder strap is another perk if you are carrying stuff to and from your car every day to work or to drop your baby off at daycare. 

Easy-To-Clean 

You will soon learn that spills and leaks when pumping is common. It is important that your bag is easy for you to clean when this happens. A bag that is wipeable is best because you will likely be out at work or traveling – no access to a sink or washing machine. 

Having one that is machine washable is a HUGE plus though because you can always throw it in the washing machine when you get home to get a good deep clean – much needed if you are using this cooler day-to-day.

I have included the best coolers for breastmilk in all sizes below, so hopefully, you can find a great one that fits your needs.
