To be honest, I continue to use an old Peter Storm fleece I bought from Millets about 10 years ago. This has since been on trips both home and abroad, and has adequately done the job it was bought for.
It is a bit bulky, so about 4/5 years ago I bought a Mountain Equipment Windstopper, but these are quite expensive (it was in the sale at the time). I’ve yet to take it on a trip though, as I can’t quite break from my trusted Peter Storm.
