I read up about using Tyvek cloth to make a bicycle-touring rain cover for my bike and thought it was an excellent idea. Tyvek is a breathable material made by the DuPont company.
Well, Tyvek protective gear is made for biohardardous material. They make disposable pants/shirts/jumpsuits/coveralls/hoods etc. You can buy a pair of Tyvek pants with an elastic waist for less than $3.00 and a jacket for less than $5.00 (USD).
Has anyone used Tyvek protective gear for the cycling wet-weather gear? If so, how breathable and comfortable is it? How much does it hold up to abrasion and how long does it tend to hold up?
