Used a Thermarest Z-lite Sol as the main pad and my Multimat as the shoulder insulation. Temperature got down to ~40F, and I was quite comfortable. The pad opening is only on one end of the hammock, so you have to slip it in and push it down, which was a little tricky with the "accordion" Z-lite, but not too bad. The extra length of the 11' hammock allows me to sleep right down the middle, not on the diagonal, which makes pad use a little simpler.
