Lightest Material for Tarp?

[CrankyOldGuy]

...where are you getting your Tyvek? I'd like some to just play around with and the stuff I have isn't real light at all. That's if you don't mind sharing.

They also sell on Amazon.

8 oz is great! maybe youre at the point where reducing weight comes down to the tarp design, not the material used? If you can get by with a shorter hammock, you can use a smaller tarp, that uses less material etc.etc.

Pretty much. I used 1.1 to make the Asym design on backwoodsdesign.com.
Will have to field test to see if I can make any adjustments to the size.

I ordered a cuben hex custom tarp from Hammock Gear. Should come in round four ounces give or take a few grams.

I found a partial roll in my garage - don't know where it came from. I'm always fascinated by what I find in my garage.

Depends on what kind of Tyvek you are using. According to Zpacks the home wrap verion of Tyvek weighs in around 1.85 oz per square yard. Most finished "1.1 oz" silnylon weighs in at 1.3-1.4 oz. There are other lighter Tyveks but they may not be durable enough for a tarp. Here is a chart from Dupont. Kind of hard to read, but you get the picture.

This Australian vendor makes silnylon and Tyvek tarps.

His Prospecting Tarp weighs 490g (17.28 oz) in Tyvek, and 560g (19.75 oz) in Sil-Nylon. Not sure what kind of Tyvek he's using.
