Hey, I was reading some trail journals a few weeks ago and someone (whose trail name I've forgotten) talked about using tyvek pants for rain gear. I'd never heard of such a thing and after a quick check around the internet I saw that they're very commonly used in factories and industrial type of jobs for chemical protection and whatnot. And fairly cheap, too.
Has anyone here used tyvek pants/pullover smocks as raingear on the trail? How long did it last? Clearly it's meant to be disposable, but I would hope it lasts longer that a day (or a couple of uses).
