Chip said:I just revised my choice. My sons Thermarest over a RidgeRest melted no snow last night, while my Thermarest over ensolite melted PLENTY of snow.
I just ordered the large, wide Ridgerest to go under my large, wide Thermarest.
Maybe you produce a lot more heat than your son?
Old white ensolite also becomes brittle and breaks into many pieces at -20F. (Green does better, but either is much heavier than modern closed cell foam.)
