I waited to review the bag until I had used it for a while to see if my opinion changed. I really wanted to love it, but I don't. I got this bag because it has a lot of pockets and it seemed like I could put all of my work and pumping items in it. Unfortunately the pockets aren't designed to all be used at the same time and if you use one pocket, it cannibalizes the space from another pocket. The outside pockets are just flat to the bag so even a phone seems too thick to be in there comfortably. The elastic top pockets on the inside are decently big, but also awkwardly tall and anything you put in them falls to the bottom of the bag and interferes with the side pump pockets. I can hardly zip closed my medela cooler into the pocket for this reason. Anything loose in the top of the bag falls in the space between the lower compartments and has to be fished out later to close the bag. Using the laptop sleeve makes the top of the bag hard to zip closed because it's makes the bag too rigid. The bag is very snug with a spectra, but even after getting a smaller portable pump I'm still not feeling like the space in the bag is well utilized. It does work much better than the pump bag I got from insurance, but I still have to carry my lunch bag and a purse in addition to this huge bag becuase there isn't enough usable space.
