Awesome. That was my main worry, that I'd be soaked from the sweat rather than the rain!
I'll have a look at the weekend in my local shop and if they don't have much I may plump for a set of these. Are either of you tall? The inside leg for the 32" waist is 32" and the 34" is 33" inside leg, so the only thing is they may be a little short (would probably order a 34" waist) but if they tighten down at the bottom of my legs they should be ok.
I think that's mainly down to the person, I don't sweat either and that's with
Jeans - Textiles - Waterproofs
T-Shirt - Jacket - Waterproofs
However that's just because I'm moving most of the time. No basic sealed waterproof will be breathable by the sheer fact that they're waterproof. £20 ones will be just as breathable as more expensive ones unless it's something like gore-tex but they're £££££
