I'm having a horrible time at the moment with menopausal hot flushes, and I need to find a lightweight, breathable raincoat that won't make me sweaty! On days like today, when it's warm but pouring down, I'm reluctant go out because after an hour or so I'll be drenched in sweat (sorry, TMI) to the extent that I might as well have got rained on.
It's difficult to tell how breathable a coat will be in the shop, as you can't really put it on for long enough to find out, so some recommendations from experience would be great!
