I have been using tyvek as a ground cloth in the most in climate weather you could imagine and it has "never" left me wet. Hope that helps...Happy Trekking...sabre11004...

I don't know what type of tyvek you had but the normal "house wrap" tyvek will not leak. If it did every home in America would be wet rotted. This is the material that goes on to seal 90% of the homes in America.They depend on it not leaking, however, with that being said, there are different types of tyvek and they all probably are not water "proof" but then used for something different.


Actually, most houses have a layer of construction (siding, brick, stone, etc.) over the Tyvek. Its purpose is to block air infiltration, not water.

This is not correct - Tyvek is not completely waterproof - only highly water resistant, at least according to DuPont.

Silnylon will not 'leak' under high pressure. It will 'mist' very gently under extremely high hydrostatic pressure. However, most shelters made out of silnylon are shaped to resist any sort of pooling of water and reflect such pressure. In my experience I have only had misting one time, and it was ever so slight, during a 40 mph rain / wind storm. I was unable to use any natural wind breaks in the area.

It was not the "chili" that split the suit, but you wouldn't believe me if you saw how it split. I will also say this about the Tyvek I used, if you touch anything, the water will come through. I'm sure the heavy duty suits some have mentioned are better at keeping water out, but make sure you know what type you're buying, lest you find yourself a victim of the "chili" <img src="/forums/images/graemlins/grin.gif" alt="" />

They are a nice emergency item to have, that you don't have to worry so much about taking care of, though using a sheet of Tyvek as a type of blanket would probably work better than wearing the suit, for various reasons

People don't understand tarps that are "different" from the norm...some people are just "hydrophobic" about them . We should just be tolerant of other tarps life choices, is all i'm saying <img src="/forums/images/graemlins/grin.gif" alt="" /> Don't be so "hydrophobic!"
