You're welcome and great question!

The Tensor Insulated Pad uses an aluminized film to reflect your body heat and prevent heat loss on cold nights. Personally, I have used both insulated and non-insulated sleeping pads in all seasons and have not noticed a difference in warm temperatures. Most of my experience is in the Pacific Northwest and Alaska, however, where it is rarely warmer than 75° F at night. As such, much of the performance will depend on conditions around you and how you tend to run (cold or hot). Additionally, I tend to run very warm and I regulate my temperature by opening up my sleeping bag (or not using one at all if it is warm enough). If I am sleeping in conditions that are hot enough to make me uncomfortable, I find that removing the sleeping bag from underneath me and sleeping directly on the sleeping pad helps keep me cool, even with an insulated sleeping pad. 

Hopefully this helps, thanks!
