I wanted to share with everyone the new sleep system that I have found to be quite effective.
The Gossamer Gear GVP airbeam pad+1/8 thinlight and then my upgraded prophet with inflatable frame makes a nice place to put my feet.
This system has done me toasty down to 35 degrees with a 20 deg revelation+fleece+hoodlum and I think it could go lower, high 20s maybe.
I was intitally skeptical of the GVP pad but once I learned to sleep on my back with it mostly deflated and on my side as inflated as it can be, it truly is comfortable. (more so than ccf at least).
Side sleeping is not the greatest and my arms will often go numb but I can usually make it 6 hours on my back so I am sure with more practice I will be able to stay on my back.
This is I think the lightest option for some form of air matress with included ccf foam protection on the bottom. The torso mat looks robust and I have had no issues for 12 nights after sending back a defective one to GG who quickly replaced it for free.
I posted this because I remember no information was available on this pad on this site. I also posted here because it is indeed a system rather than a single item and would not do well in the reader gear reviews in my opinion.
