1.25oz tyvek leaks so now what on 08/14/2009 14:35:53 MDT Print View

Got it from Quest, folded some square into a cone and it drips. Maybe okay for a temporary sun shade tarp or a bivy under a tarp or in a tent that wont have to handle too much water.

I had hoped it would be more waterproof.

So now I am looking for a breathable material again.

What I want is a breathable truely waterproof fabric for a bivy. I like to sleep under the stars at times, and if I get caught in a short shower at night, I dont want to have to worry about getting soaked.

I would also like to build a gatewood type shaped tarp out of some sort of breathable material although I could probably just use silnylon for that.

Thanks

The best stuff I've found so far is Epic Malibu, used by Black Diamond, about 1.8 oz/sq yd. It is occasionally available at thru-hiker and some other sites. It does not meet CPAI specs. Looking at the Essence and Mica jackets, I suspect that lighter and more breathable materials will become available soon. And from this forum, there is much info about the Tyvek. For my next project, I am going to go with the Epic, well vented.
