I run hot. I sweat buckets in the gym.
I currently get by with just a thin base layer in the hills with a TNF Pursuit jacket over if it is windy or there is anything more than light drizzle. I have found it to be a cheap, decent jacket and reasonably light. The hood seems a bit crap when you try them on but it sits fine with a pack holding shoulders down, not tough enough for climbing at all I would think but I have gone arse over tit a few times in it and its without a scratch.
Currently baselayers favourites are a Rab Interval t shirt or a Saucony Active Fit running top. I'd never wear something like a polycotton shirt as I would just drench it and it doesn't add anything. It is a personal thing though. I wouldn't consider wearing more under the jacket until it got down around freezing while I was moving or only taking short rests.
I've been using that combo for about 3 months, mostly around N Wales, and haven't had issues with getting wet from inside in the wet summer we have had and I am probably out 3 days a week in all sorts on average. Including the mental stormy downpours and the sticky drizzle before. This is probably because I wear little underneath and keep moving as much as the shell itself. I have got wet a couple of times in the torrential stuff that has forced through the hood/down the back of the zip and so on but that would have happened with anything. I have also managed to walk myself dry reasonably quickly.
I rarely carry over-trousers unless I know it is going to hammer down all the time. Even then I would probably just suck it up in the summer. The over-trousers I currently like are my Montane Astro Ascents. They are nowhere near light but they fit me well enough to be happy just wearing them over some light running leggings when it is cool. I have various light weight shell pants I could take but I generally don't bother.
I've got quite a few bits of clothing I have collected over the years. And I have worn some favourites into the ground. I'm currently happiest with a jacket that was only £90. I reckon I will get a year to 18 months out of it as it is a lightweight going off similar event/hyvent stuff I have killed.
