My trusty backpack is falling to pieces. Any recommends for a new one? It needs to do all my current one does - hold everything I need including picnic, snacks, water bottles, kids raincoats and a couple of toys we really don't need but have to come anyway. But, this time as I'm not 18 and travelling, I'd like it to look a bit stylish. Any ideas? I don't want to spend a fortune but I do want it to last a while. What do you use for day trips with children?
