The Todd-Tex for Bibler and Intergral Designs is waterproof and breathable, but high tunnel vents are still needed. The fabric is heavy and expensive. They have been state of the art alpine tents for many years.

Epic is breathable and highly water resistent. Black Diamond makes tents and bivies that are light and expensive.

TarpTent makes a Tyvek tent that is highly water resistent and breathable. It is well designed and affordable.

The owner of eVent fabric will not allow eVent tents because of fire standards. I have an eVent bivy and it is light and expensive, but performs great.

I use a DriDucks poncho as a warm weather bivy. I like to sleep under the stars and pull it over me if it rains.
