I have a couple of Big Agnes bags for my son and I and Thermarest pads too including the waffle foam backpacking z fold versions. The BA bags especially rock in a Hennessey hammock which I use quite a lot because the pad never separates from the bag; it's in it's sleeved pocket; great idea. We use the BA insulated air core (they have more than one pad) and the only drawback so far is that will take your breath away (it's not self inflating) at altitude filling it, but it's worth the effort.
That said I have the Camprest version of the Thermarest and have for many years and it always works.
