100g-ish rain jacket?

Rab has a waterproof/breathable pullover 2.5 layer (the “Phantom”) at ~ 3 oz (91g).

just as pricy is the gorewear r7 trail running jacket. A bit heavier (117g size M), but won’t wet out and the most breathable rain jacket I have worn. I have been happy with mine. Most of my experience has been cycling, trail running, and day hiking because my backpacking trips have been mostly dry (bloody drought). General observations on my raingear page, some notes about Shakedry performance on my Norvan SL review.

The Raidlight Hyperlight MP+ hooded rain jacket is available at runnerinn.com. Weighs about 92 g (M).  $178. I don’t have one, but I know a lot of  mountain racers prefer Raidlight gear, especially their running packs.
