North Face Apex outer shell, with an extra layer of insulation underneath. I don’t like wearing my waterproof as the mud erodes the fabric and ruins it.
If it’s proper biblical or particularly cold then I might wear it, also got some waterproof shorts but these usually only come out at 24 hour races. If I do choose to wear them then I use a front and rear mudguard, to keep the crap off the jackets.
Generally if it’s warm enough for sweating to be a real problem then it’s not cold enough for rain to be a real problem, I reckon.
Of course the advice re mountains is good – go prepared.
