Keeping your pumped milk at the right temperature when you travel

When you’re a breastfeeding mum, traveling with your baby in any capacity can add a few extra layers of complications and stress, not to mention several additional items you have to pack in your luggage and diaper bag. 

Your baby’s feeding schedule and travel schedule seldom align perfectly with each other, especially when keeping with a flight schedule or on road trips.  On many occasions, I’ve had to pump before/after a flight or while in the car and save my milk for later feeding.

In all cases, it’s best to have an insulated cooler for breast milk on hand, as we all know how precious that liquid gold is! The best cooler for your needs depends entirely on the duration of your travel time and your travel surroundings, and that’s why we’ve compiled a list of the Best Baby Bottle Coolers For Travel for almost every situation to help you find the perfect one.

What to look for in a good breastmilk cooler bag for travel

Several factors go into choosing a good travel breast milk cooler bag, especially one that is versatile enough to fit your specific needs.  It’s important to consider each of these before you select one for purchase.


Choosing a breastmilk cooler bag with quality insulation is essential regardless of where you’re going or how long you’ll be travelling. Knowing that your milk will stay at a consistent temperature gives you peace of mind and is also necessary for your baby’s health and safety. 


If you’re travelling a long distance or will be gone for several days without access to a freezer, you’ll want to choose a milk cooler bag with a larger capacity.  This will allow you to put a sufficient amount of ice/icepacks inside along with your baby bottles or breast milk storage bags. 

However, a more compact option would be best for flights or car travel, as you will be in a more confined space and won’t be travelling without intermittent access to a hotel fridge or gas station. 

Cleaning and Care

The best cooler for breast milk will be easy to wipe clean, or you should be able to toss it in a washing machine for a cycle to reuse.  You’ll also want to look for a bag with a stain-resistant outer surface as well, as we all know how easily items can get soiled during travel. 

Stylish vs. Practical

As mums, we’re often torn between what looks the most stylish and what is the most reasonable and practical option.  Luckily, most breastmilk cooler bags are a combination of both.  They often come in a variety of colours and patterns to suit your personal style, and many choices offer both tote and strap-carrying options so that you can adapt them to your immediate travel needs. 

Method of Cooling

When it comes to choosing the best coolers for breastmilk, you have a few options in terms of cooling.  The most common cooling method is an ice pack of some kind.  Most breast milk cooler bags come with an ice pack that is made to fit that particular one.  You can also simply use freezer bags full of ice and replace them as needed. 

You can include your baby milk bottles in your family cooler too. Just be mindful of how often this will open, and consider whether a consistent temperature can be maintained for your breastmilk in the larger coolers we describe below.

The final option would be a cooler powered by electricity.  In my opinion, this is the trickiest and least available way to go.  If you are embarking on a long road trip where the mini-fridge can be plugged in, it might come in handy.  However, you always run the risk of the cooler or (heaven forbid) your vehicle breaking down and finding yourself stranded in more ways than one.

TSA Rules Regarding Transporting Breastmilk

If you plan on traveling with your baby by air, we strongly recommend that you review TSA’s rules regarding breast milk, formula, and other baby items.  As it currently stands, you can transport “reasonable” amounts of breast milk in your carry-on bag. 

We also recommend you check with the TSA agent at your gate for additional guidelines. 

We have a detailed guide to breastfeeding and travelling with breastmilk that may cover many more of your pumping and breastmilk transportation questions. 

Short Trips vs. Long Flights

The type of breast milk cooler you choose strongly depends on whether you’re planning a short flight (either directly or with a single layover) or longer flights with multiple layovers (or to another country). 

A shorter flight may not require the same level of insulation, as you’ll be able to replenish your supply of ice or find a fridge in your hotel within 5-6 hours.  However, if you and your baby will be enduring an 8-hour flight plus additional driving time, it would be wise to find a cooler that offers significantly more insulation.

Best Cooler Bag For Breastmilk Travel

Let’s dig into all the details now on the leading brands of breast milk cooler bags for travel; noting that there’s no one-size-fits-all, and you may need different bags in different travel scenarios.

Best Overall Breastmilk Cooler: Skip Hop Insulated Breastmilk Cooler

Why We Love It: This is an all-around crowd-pleaser that is versatile enough to be used in many different travel situations.  It’s compact enough to fit inside a diaper bag or backpack for air travel and fits nicely into a free spot for shorter car trips. Previous customers have stated that it keeps several bags of breastmilk cold for around 8 hours.

Possible Cons: This milk cooler bag is best suited for shorter trips, as it can only carry two full-size bottles or 2-3 milk storage bags.

Other value options to consider

Most Compact: FlexiFreeze Pocketbook Breastmilk Cooler

Why We Love It: If you’re only travelling for a few hours before having access to a fridge or additional ice and want a discrete option for storing several bags of breast milk, this is the breast milk cooler bag for you. It’s the size of a wallet and can easily fit into your diaper bag or purse.  It has built-in ice cube packs, so you just have to take it out of your freezer and ready to go.

Possible Cons: Works best to keep frozen breastmilk cool, so less suitable for storing room-temperature milk for long periods.

And don’t forget your ice packs!

Not all of the insulated breastmilk coolers we’ve described here actually come with their own ice pack. Some coolers have their own branded ice pack you can buy separately, like Yeti & Coleman. Otherwise, generic ice packs are fine. We prefer soft contour ice packs for a better fit.

Ice Packs for Coolers, Breastmilk Bottle Storage, Lunch Box, Insulated Bags, 4-Pack Contoured Freezer Packs, Long Lasting Reusable Cool Packs for Canned Beer Soda, Camping Beach Picnic
Healthy Packers Long Lasting Ice Pack - Great for Breastmilk Bottles Storage and Can Coolers | 4-Can (2 Pack)
Thrive Ice Packs for Lunch Bags - Reusable Ice Packs for Cooler and Lunch Box - Long Lasting, Lightweight, Soft Gel Ice Packs for Camping, Beach Bags, Picnics, Injuries - Pack of 4

We hope this breastmilk cooler guide has helped you narrow down the choices and sees you one step closer to confidently travelling the world with your kidswhether it’s a day hike with your bubs or flying around the world!
