In reply to TobyA:
I actually use my vaguely similar Norrona thing (although windstopper upper and a little less of it) as a Spring/Autumn soft shell for long distance wandering etc in the UK. Basically just a deluxe windshirt with a very, very nice hood, pockets etc.
The air permeability helps there with being able to keep wearing it under most conditions.
Not what its designed for and objectively considerable overkill - especially in terms of price - but the functionality is probably a pretty good fit to the needs.
