The jacket that I'm using is a Rainshield O2. The material is very thin like Tyvek. I had concerns about durability but bought one at the start of last summer. It's been on several trips and lived in my saddle bag the rest of the time for commuting. I don't wear it continuously, just when it rains or gets unexpectedly cold. So far it's held up, but I've seen others patched up with tape. I'm not very worried about it's durability.
