Reviews of the Best Cooler for Frozen Breast Milk When traveling

1. MOJECTO Large cooler bag



When you have no access to a freezer or refrigerator when traveling, the Mojecto Large Cooler Bag is the best option.

This cooler bag is insulation using high-density thick foam and has two heat-sealed thick peva liners, which ensures that the baby’s milk is kept cold.

All the compartments are highly insulated with the thick foam. This includes the top and the bottom compartments.

The manufacturers recommend that you strictly use ice packs and ice gels that are specifically made for cooler bags and lunch boxes. You do not need to use homemade plastic ice packs, open ice, or open liquid since their sharp edges can damage the liners. However, this cooler bag comes with an extra liner for replacement in case one of the liners is damaged accidentally.

MOJECTO cooler bag has a large capacity. It can hold several bottles of milk or milk storage bags, food and drinks thanks to the many compartments, netting pockets and normal pockets. For instance, it has a large front pocket with a zipper with two mesh pockets on the inside.

In case you order to this bag and get a defective or damaged one, there is a lifetime warranty so you can have the bag replaced immediately.

Pros

  • Large capacity (multiple compartments and pockets)
  • Long lasting cooling
  • High-quality heavy-duty material
  • Thickly insulated
  • Lifetime warranty

Cons

  • You must use ice packs or ice gels made for cooler bags and lunch boxes (no homemade ice)
  • A little bulky for light travel

2. Sarah Wells Lizzy Breast Pump Bag



The Sarah Wells Lizzy Breast pump bag was designed by Sarah herself with pumping mamas in mind. She was inspired by her experience and that of other pumping moms to produce this pump bag. So you can rest assured that it meets all your requirements.

To start with, it has several compartments that can fit different portable breast pumps. Actually, it is the most preferred bag for moms with Spectra S1 and S2 breast pumps. It is also compatible with brands like  Medela Pump In Style, Freemie, Philips Avent and Sonata among others.

It has two thermally insulated side pockets. The bigger side pocket is meant for the breast pump while the smaller one is meant for bottles and pumping accessories.

If you want to carry frozen milk or keep freshly pumped milk cold, you can add ice packs in the thermally insulated pockets and then put your bottles. This can help to keep breast milk chilled for up to 6 hours.

A unique feature that we love about this pump bag is that it is very discrete. You do not have to remove the whole pump from the bag when pumping. Simply unzip one end of the pump bag and connect the pump to a socket.

The inside of the bag is quite huge. You can put your personal items including a laptop when going to work so that you don’t have to carry another bag.

This cooler bag is not only attractive but also trendy and fashionable. It comes in a variety of prints and does not look like your ‘normal’ cooler. Actually, once you are through with breastfeeding, you can use it as a diaper bag and carry your baby’s food and drinks in the thermally insulated pockets.

Pros

  • Lightweight
  • Durable
  • Variety of prints
  • Easy to wipe clean
  • Lifetime warranty
  • Thermally lined pockets
  • Large capacity

Cons

It produces a little sound when it is working but not too loud to wake a sleeping baby. In addition, it produces very little heat hence no overheating.

This cooler is best suited for road trips and picnics where it can stay connected to the car’s cigarette ignition all day for maximum cooling.

A unique feature in the PackIt Freezable Lunch Bag is the freezable cooling technology, which makes it possible to freeze the entire bag.

Unlike other PackIt lunch bags, this particular one has a shoulder strap and it can hold 30% more. The shoulder strap can be adjusted according to the needs of the user.

Moreover, it has a zip closure that ensures that the frozen bottles inside the bag are completely locked in so as not to start thawing.

The bag is constructed from non-toxic material; thus, it is free of BPA, lead, phthalates, PVC and formaldehyde.

In addition, it folds completely flat, which helps in storage in the freezer.

If you are planning to travel, you should freeze the bag for at least 12 hours overnight so that the walls can be completely frozen by the time you put the breast milk bottles.

In addition, it can hold up to 4 Medela bottles since the ice pack is molded to fit 4 bottles.

In case you need to carry more breast milk, you can squeeze storage bags around the sides of the bottles. Thus, this cooler bag is perfect for transporting milk from work to home or leaving at day care.

Moreover, it easily fits into Medela Freestyle and Pump in style breast pump bags.

Moms who have used this cooler bag explain that it can keep milk freezing cold for 8-9 hours. Others have managed to keep the milk cold in this bag for over 15+ hours. This shows that as long as the ice pack remains frozen, the milk can stay freezing cold in the bag for long periods.
