Vin your looking to hard,,,,the most waterproof stuff ain't always the most breathable ,,,,them Dpm gortex over trousers that our army use are very good,,,wear joggers underneath mate,,, I'm lead to belive that the same jacket is good as well,,,,ask socks mate
I liked them fleck tarn gortex overt trousers ,,,bib and brace style,,,but they are thinner than the Brit ones,,,, good thing about you is,,,,you will get a pair to fit ya..
