Thank you all for your replies.
Having looked at the Fjall Raven site I've realised another facet of my quest - you see, I'm only a 32" waist and a lot of this gear seems to start at 34" (why is that?).
As for cotton... I live in Snowdonia and have a neon-like sign that blinks "cotton kills". Ventile then? Expensive, but is it quiet? Anyone wear ventile?
Wool might be good for the winter - anyone reccomend a good wool trouser?
Thanks again
Swedish sizing. As a UK 32" you should be a Swedish size 48.
