One tip I would recommend ..although it's not strictly about trousers is wearing..sealskin socks..bit pricey.. (£35) but they can go under your favourite boots and keep your feet completely dry.. Gore text is fantastic but if they get wet inside they do take ages to dry. And when space is at a premium you can take the socks just incase, and not have your feet bake in gortex when the weathers warm...
