Mothers love Medela's Cooler Bag because it keeps breast milk cold while they're on the road. You can use this Medela bottle and cooler set as a backup container to bring your breast milk home from work. You can also leave it with the daycare facility.

Advantages of a Cooler Bag
No matter where you need to take it, the Cooler Bag keeps breast milk safe and cold. The curved ice pack maximizes the amount of time that breast milk may be stored and is specifically made for Medela bottles.

The expressed breast milk will stay colder for longer thanks to the insulation on the interior of the bag.
A separate chilling element and four Medela breast milk bottles are included.
