Rapha, nice but a bit pricey?

I would recommend either the rain jacket or classic wind jacket, recommend the latter as it fit quite small in a jersey pocket.

Where are you that it's always cold and wet?

I'm in Gloucestershire...obviously the cold/wet was in Jan/Feb...hence me looking for something more lightweight & un-sweaty now.
I've got the wind jacket...which is great for chucking in the pocket "just in case", but I was wanting a jacket to wear when it's already raining...so fully taped seams etc
