Having recently discarded one that was gifted a few years ago, I can say that the "best" rain jackets are essentially Formula 1 supercars. They have low lifespans by design; even if you are careful with reapplying the magic reconditioning formula, you will still sweat on it. Eventually the tape covering the interior seams will get wet. Then moisture gets trapped under the tape, and at that point it's just a moldy windshell. In contrast a simple leather jacket or rain poncho is fine for everyday "it's a little rainy" or "it's really rainy" scenarios. If you are using the ultralights effectively, it's probably in a sportive context where you are going to use it just for that sport, for a few seasons.
