They may have changed the design a bit from previous reviews but I have no problem with my large Spectra S2 pump and black Medela 4 bottle cooler there (with ice), PLUS my laptop, notebook and various other items. The trick is to install the pump first and then the cooler. Please note that the cool box does not have to be pushed completely into the body of the bag - for this reason the bags protrude slightly on the sides - this offers additional space. In the pocket on the other side (not the cooler bag) I have room for other small items like snacks or baby food bags. On the back of the bag there is a separate compartment with a separate padded laptop compartment. It fits my 15" laptop perfectly. I also put my laptop in this compartment, it's about 1" thick. Again, it's easier if you load the pump first and then all the other items. A few things that I would have liked to have done differently, but not bad enough that I would return the bag: As others have said, it would be nice if there was a divider in the main compartment between the pump compartment and the rest of the bag.It's annoying to tidy everything up, what fell off when I take out the pump to put the pump back in. Also, the outside pocket at the top barely fits my keys and phone.If you have more than one pair of keys on your keychain or a large smartphone, you will feel very comfortable .I regularly travel with two phones (one private, one for work) and usually put one in the main compartment if I need to pack both.Overall I found it value for money pretty good. I've been using it 4-5 times a week for 2 months and so far it's holding up well. It still looks like new, the zippers work perfectly (but a bit noisy) and most importantly, it's comfortable to wear, although I often pack it up completely. I also like having handles on top if they are easier to carry than carry. It doesn't scream "mama sack" so I'll probably keep using it even after I've stopped pumping.
