I own a 10'x10' siltarp, which weighs 1 1/2#. I'm going to give this a try. I think this will work well for 3-season backpacking. I'm skeptical about how well it will work in winter weather.
Watch until about half-way through the video to see how it looks with the awning pulled out.
Wind in my hair, Sun on my face, I gazed at the wide open spaces, And I was at home.
