Thanks, Andrew. It sort’a looks like Nemo has hit the limit with making dimples in CCF pads. As you say, they look like they are crushing and perhaps staying that way over the time you spent out with yours (note the winkles/creases in your picture) and the metalic coating does seem to be wearing. I also have concerns about long-term durability. Unfortunatly, you did not say how long you had it out. From the looks of the pad I would make a guess of only about a week.
The “dual-density” is likely a manufacturing requirement. You were correct in ignoring it. It supplies a bit of negatives by introducing harder outside layering with less rebound, but takes a shape a bit better. Unlike the sliced evazote foams, this probably introduces a little less Rvalue and less resiliency for the entire package.
A good evaluation between the two major types: Zrest style and Nemo Style. As you say you noticed no practical difference between the two in use. My “druthers” would be to buy the US product over a foreign product if there is no difference. It is a few dollars cheaper, anyway. But, if I didn’t have a choice, there is not enough dollars involved to make one highly desirable over the other.
