Even if it is a little heavy - it would be a great car camping tarp. Excellent for over the picnic table to keep the whole crew playing cards well into the rainy night.
I wonder if their Silicone tarps are made with the same material that Sea to Summit is using for their dry sacks - it's called Ultra-sil (different from the Ultrasil I use) and is coated silicone on one side and urethane on the other). Anyone know who manufactures that brand of silnylon? I'd like to get some to play around with and test.
