User Review: Therm-a-Rest Men's ProLite 4 (Large)
Price Paid: $104
This is the best pad I have ever used. I went hiking using a 40 degree rated bag in 35 degree weather and I was still warm on my backside. It prevented the heat from going through the ground. Even though it fit me perfectly (I'm 6'4"), it packed very small and light in my pack.
