The two 'standard' insulated air matresses are Big Agnes Insulated Air core and the Pacific Outdoors Thermo 6. Both will keep you warm down to the upper thirties, colder if you sleep warm or use a closed cell foam pad over it. My Thermo 6 weighs 22 oz. Stephensons DAMs are supposed to be both warmer and lighter but I have no experience with them. For even better sleep I switch to a hammock.
