I am returning to work soon. Please recommend a bag which is able to put all the breast pump equipment ( BM bottle / flange / breast pump / cooler bag) and also my laptop. I would prefer shoulder bag instead of bag pack as more convenient to take train and buses.

Like what the other mummy recommended, I have a friend who is using this Sarah Wells Breast Pump bag. She got it as a gift from the colleagues and absolutely loved it. Fits her S1 well and could fit other stuff (can fit her laptop as well, which she sometimes brings to and from work). Looks good too! https://www.amazon.com/Sarah-Wells-Kelly-Convertible-Breast/dp/B0128S0EXY?ie=UTF8&keywords=sarah%20wells&linkCode=sl1&linkId=82d1150cfb06bfeed4207aa1da5e3ab6&qid=1456713739&ref_=as_li_ss_tl&s=baby-products&sr=1-1&tag=beinspibecrea-20

Try searching "sarah wells" bags. Their bags seem good! I dont own one though

jujube or skip hop seems quite popular too

I used the Kate Spade diaper bag
