I bought a zpacks ground sheet here that was supposed to be a bathtub but turned out to just be a flat groundsheet. I already have a polycryo groundsheet that is flat so this doesn’t seem like much of an improvement.
I took my pocket tarp out in the rain and got a little wet because I rolled part way out of the tarp enclosure in my sleep. In the morning, it occurred to me the slight hexagonal shape of the groundsheet might provide for a makeshift door to give me better coverage on rainy nights.
