In reply to RJP:
They seem to have done something bizarre with their sizing - the old Karakorum pants in Goretex have very different fit - I replaced mine with the new model this year and it's really noticeable. I also found them hopelessly baggy round the waist, but a size down has really short / narrow legs (crap when you have normal length legs and "chunky" thighs). A shame, as ME used to be a good fit on me. the flappy waist seems perfectly designed so that all the extra material is to the rear, so I always seem to end up with a flap that water can get down through and wetting out from the arse outwards on dreich days.
Cheers,
Stuart
