i wear goretex boots and jackets and craghoppers pants.
bergaus,north face,paramo,mountain gear etc are all totally waterproof.they are not cheap though but work and keep you dry without sweating too much!!!
i bought a bergaus "hurricane" goretex jacket yesterday.this is for leisure mainly but i will use it for collecting.£162 from go outdoors.
then i have a shorter goretex north face jacket for work which was £150.great jacket.i wear a fleece underneath and it keeps me totally dry and warm.
rab/mammut and some of the other mountain/ski gear is even better but they are even more expensive usually but these are for very extreme conditions.
i find the goretex stuff very comfortable and light..........oh and did i mention they keep you dry?
goretex boots everytime .the bergaus boots are fantastic IMO and they are lightweight,fit well,very comfortable and keep my feet bone dry.they usually last me around 18 months worn every day for work before needing replacing.
hope this helps
