I have just 2 pairs of trousers, Fjallraven Abisko for when I'm at fighting weight, and the seemingly ubiquitous Craghopper Pro Stretch for other times. I seem to wear the Cragg's more often than not.
However, I'm not sure how funny I'd find them in winter or with a bit of sharp wind ..... I'm heading to Wicklow next week with them, so I'm about to find out myself
I'd also echo a wee bit the sizing comment above. I have the 38 waist model but its more like a 37 IME ........ if you were planning on wearing some thermals underneath I reckon it'd be snug.
Try before you buy, but if you do fit them then I don't think there can be much better trouser for your buck
(unless someone close to you stocks Prana Stretch trousers, which I've read very nice things about)
