I've been through the thread about changing bags and loads of people recommend the skip hop dash - some say it's v spacious. We currently have it, and one in cloth and it is full before snacks etc get added.
We will have 2 in cloth come September, so it is not going to be big enough. it needs to hang on our double decker tandem which doesnt have a basket when 2 are loaded, and not hit the bottom rider in the head, and it needs to also be carriable not just by hand handles.
Anyone got any fab ideas? otherwise we will be looking at what we can clip onto the skip hop in a bag lady kind of way!
