I have many tarps, one of them being the HG Cuben Camo. I love this tarp because of it's already reported 7.5 ounce weight.
I dont like the fact that it doesnt compact down like my Superfly though... takes up way too much space in my pack.

The tarp that I use the most... or my go-to tarp is actually a DD Superlight (not so light at 1lb) but I love this tarp... perfect for hammocking and even better when I'm above tree line here in Colorado and I want to tarp camp, this tarp is built for both and packs down very small.
