Material suggestions

[SGT Rock]

Laughs aside, Tyvek is olefin, heat-sensitive, and should not see a hot iron. Temps should not exceed 175F.

1.20oz / yd2 is the lightest Tyvek. Nylon would have to have a basis weight of 1oz before silicon treatment to be that light. No comparison in cost.

So someone does make lighter tyvek?

Yes - Tyvek 1443r. It's the clothes grade version of tyvek. Think clothing for a lab. 1.25/oz per yard. Not quite as durable or waterproof as the standard Housewrap, but I have used it as a ground cloth before.

2 questions for you:
Where are you going?
What was wrong with the polycryo or window film? It is lighter than cuben, no?
Ok, that was 3 questions.

I'm tapatalkin' ya'll

Well what I have found, and it could be wrong, is polycro is basically the same stuff that is used for the laminate in cuben fiber - so like cuben fiber without the weave. My concern was it would wear out too quickly.

Would the polyester ripstop like at kitebuilders.com work for you?

[SGT Rock]

Does it repell water and is it durable?

I made a cover out of 1.25 tyvek and it came in at 122 grams which is in the range I was looking for. Now I need to trail test it.

I'm told hikers have completed thru hikes with a single polycro ground cloth. Except for the thorny desert polycro ground cloths reportedly hold up very well. I'm experimenting with some for a light tarp in good weather.
