hi goodbabyb,
i have got 2 harrods bag, one small one and one bigger one..
yes, they are strong enough to sustain the weight.. and i like their waterproof material..
we usually bring along our own hot water thermal flask & a bottle of boiled water for making milk for bb..
i also dump in extra set of bb clothings, diapers, bb handkerchief, wet wipes, milk bottle & water bottle in it..
