if that is constructed like a US poncho, with 210 ripstop, etc. it would be full of holes in most desert after a night or two on the bare ground, if you were lucky.
i like two large lightweight tarps for the reason that they are cheap, and you can double them up instead of having to fiddle with repairing them; so when you need protection, you've got it by doubling it, without having to cut your surface area to a point that makes it markedly less useful. - then when you need increased coverage, you can just unfold it and deal with any pinholes, etc.
you can dominate in any environment that way, instead of just one that has soft ground and mild weather.
you could do likewise with expensive specialty gear, but i am not into that YMMV. - although they are lovely IMHO, no need for a bivy either IME when you can just burrito-wrap up in a cheap tarp, especially when you are helping someone else warm up, who couldn't fit in the bivy with you.
great photos BTW, yer baldness.
