I carry these with me always and often use when rain/snow happens when commuting by bicycle/train to work. These are the most breathable rain pants I've ever had and they do a great job of keeping me dry.  They are not as good as stopping strong winds as nylon rain pants, but that's to be expected because they actually breath.

They do feel like they are made out of paper, but are surprisingly durable. I do wish they packed down more tightly and had pockets, but these are minor complaints.
