Hi again - wow, so many replies and experiences - thanks all ;-)
I think I will just consider your suggestions for rainwear - as well as my own specific needs - and see if I can find a rainwear that is appropriate both in terms of functionality and cost. As it is I already have some Goretex "rainwear trousers" that have positively surprised me in terms of breathability (not for biking, though) so I have a slight preference here.
Thanks again for your feedbacks & have a good day wherever you may be!
Cheers - Jesper
