This Sarah Wells breast pump bag served me well after my son was born. It has backpack straps and hand carry options. It’s also very stylish and durable. Great bag to bring to work with your pump in the bottom pocket and for trips as well. The bag is still in mint condition. Clean and from a smoke free home. Feel free to make me an offer. From manufacturer: With function and style in mind, the Sarah Wells “Kelly” in all-black does it all! With easily-concealed backpack and shoulder straps, this bag is designed for ultimate on-the-go pumping convenience and is 100% USA MILITARY UNIFORM COMPLIANT. Carefully designed in consultation with a focus group of Activity Duty mamas, the “Kelly” features an all-black, uniform-compliant exterior. The bag converts from a functional, sporty backpack to chic shoulder bag with ease and is the only designer breast pump bag with a dedicated pump pocket large enough for hospital grade pumps, such as the Medela Symphony. There’s also tons of pockets for extra storage, including a padded laptop pocket for screens up to 17” wide.
