It is open cell foam, AKA a sponge, so I don't recommend it. Moving air will steal heat from it and it will absorb moisture. . Putting it inside the hammock would compress it, negating any insulation value and would tear it up over time-- it's not as tough as a CCF pad. You don't have to use Hennessy's undercover though. You can build your own or use something like 2QZQ's undercover.
If you want to go as light and cheap as possible, a wide CCF pad inside the hammock or between the layers of a double layer hammock is the way to go. It is not as comfortable, but it will work. I would look at pads 24"-26" or more in width.
