In reply to aldo56:
I managed to get hold of some berghaus storm II overtrousers for 50 quid - think they are about 60ish at the moment but from impressions so far they are seriously good. Used to have some rab latok alpine trousers and I actually prefer these - still got a crampon patch on inside of leg, nice lengthy side zips with big storm baffle inside and the fabic seems decent and has kept me 100% dry so far (which my latoks didnt all the time - may have been faulty or something but disappointed!). The goretex hellvellyn version also seems amazing, my girlfriend just bought them,same thing but goretex. albeit more expensive at 80 quid - still a bargain if you ask me.
I am in no way linked to berghaus and I doubt I will ever pay any more for a set of hardshell trousers now I have tried these (unless they change price obviously!).
