If you are transporting a breast pump to and from work, a breast pump bag and breast milk cooler bag are essentials. You will also need extra breast milk ice packs to keep your breastmilk safe and cold while you store and transport your milk. We offer a great selection of breast milk ice packs from slim to fit any bag to replacements for your Ameda cooler tote. If your pump bag came with a soft ice pack, we recommend replacing it immediately with a hard ice pack to keep your milk at a safe temperature.
