Therm-a-Rest NeoAir Mattress
The Neo Air is an awesome lightweight air mattress. It sleeps warm and so lightweigt you will be able to shed some weight from your pack. The material is thin and you will want to double check under your ground cloth to make sure there is nothing that will puncture it but honestly, it is an ultralight pad, and double checking where you will be placing it is a small price to pay.
I have had mine in temperatures into the 20's and with my Western Mountaineering sleeping bag (spend the money on this bag....expensive but so worth it) and slept warm and very comfortable. Love it.
