I have some experience with tyvek clothing. It works fine as an expendable item - like coveralls you might use, get filthy and then toss.

In fabricating something more elaborate, I would use silnylon, a fabric that is much more durable, making the investment of my time more plausible.

How would tyvek stand up to even moderate winds - say 35 to 45 mph? I have no idea, but I'll bet there are more suitable materials.
