How to choose the best cooler bag for breastmilk
Breastmilk coolers for travel come in several styles and the best one largely depends on your specific needs.
Carrying Style
Depending on your setup and needs, you may choose between a stand alone bag vs bag that fits into a changing bag or other form of bag.
A stand alone bag is useful if you need to only move pumped breastmilk and do not need additional space for extra baby items such as changing great and clothes.
Breastmilk cooler bags of this type come in several shape and sized and they can be pretty stylish: you can choose standard shapes with short carry straps or you can pick a super handy breastmilk cooler shoulder bag, which has the added advantage of leaving your hands free,
The other style of bag is designed to fit into larger bags, so that your breastmilk cooler sits with the rest of the baby gear in your changing bag.
These bags are a great option if you prefer not to have an extra bag to look after and work very well especially for smaller quantities of milks, for instance if you are out for lunch and only need milk for a meal or two.
If you are on the market for a traveling changing bag too, these are our top picks!
Cooling mechanism
The other thing to consider, when choosing the best cooler bag for breastmilk is the cooling style of the bag, which usually falls into one of the following two categories:
Insulating breastmilk aka bags that have a built-in cooling mechanism. These bags go into the fridge themselves and come in just one piece, no extra ice pack required.
Breastmilk carrier bags that require a separate ice pack.
In this case, what you freeze is a separate icepack, which then you put in the bag to keep frozen breastmilk cool.
Size
Last but not least, you need a bag that is the right size and this depends on how many bottles/ breastmilk bags think you are in need of moving and how big they are.
The best way to make sure you pick the best cooler for your breastmilk is to consider carefully the storage containers you will use, their size and what type of bottles the bag is designed for and able to carry.
I hope you found this overview of the best coolers for traveling with breastmilk useful and it helped you find one that world great for you!
