As the summer ends I occasionally find myself wanting a lightweight rain jacket for when it's a bit drizzly and there's just enough of a chill in the air for it not to be comfortable doing what I do in hot weather - which is just to let myself get a little wet. Breaking out the full foul weather jacket is just too much in these situations. It's too hot, too bulky, too restrictive. And a lot of the lightweight synthetic windbreaker type rain jackets I've tried are not in the least bit breathable, no matter how much they claim to be. I'd be just as well off to cut some holes in a Hefty trash bag and put it over myself. Many of these light jackets, including the really expensive ones, also have really cheap-feeling crinkly, slightly rubbery fabric that's just no fun to wear. Has anyone found a lightweight rain jacket that's truly comfortable and breathable?
