Breast pump bag?

Kayla • Mom of 2 🧒🏾💙 👶🏾💙

how often will did you guys carry your breast pump out the house? I am currently picking out one thru Aeroflow and some come with bags and some don’t. Do I need a bag. Who used there’s and carried it around that often? Help plz, bag or no bag? And I wouldn’t mind recommendations about which one to pick either 😂😂😂
