In reply to Alecraeside:
Me and a lot of my colleagues wear the Montane Terra pant. They're not truly a softshell pant, but work in the same way. They are really comfortable, really light, breathable and dry quickly. I'll wear them for anything in the spring/summer/autumn in the UK hills, overseas trek-ins to mountains and general outdoors stuff.
Probably couldn't recommend anything better in that category!
