I went back to work full time a week ago, and this bag has been perfect! I’m shocked that it doesn’t have more reviews. I have the Willow pump, and this bag fits my pump, snacks, my babies bottles for daycare, and a reusable bag I use to store my pump parts in the fridge between sessions, with so much room to spare! I love that it has a cooler that fits right in it, when I’m done pumping I can just throw it in the fridge. What really sold me is the exterior pockets for keys, phone, etc. because none of the other pumping bags I saw had any. This is a perfect purse/ pump bag combo for work, and it’s nice that it’s a backpack so nothing is falling off my shoulder while I’m getting my baby out of his car seat or off the floor, etc.
