The large capacity Symphony/Lactina Cooler Carrier has two zippered compartments that open on the top of the carrier. One compartment is for your breastpump and accessories. It will fit the Medela Symphony or Lactina breastpump and accessories quite comfortably. The other compartment has a reflective lining to retain the cold. The cold storage area is designed to cool and store 4 of the 5oz. bottles of mother's milk for up to 12 hours. There are two set of handles -- carry handles, and a shoulder strap. The shoulder strap is adjustable for comfort, and can be removed. The easy-care fabric can be wiped with a damp cloth, or machine washed in cold water. Bottles and cooling elements are not included.
The picture shows a zippered compartment on the side of the bag. After a recent design change, the bag no longer has this feature.
