Hi  there,

Has anyone used the First Ascent Ultralight Insulated Mattress? It quotes an R-Value of 3 and I wonder how accurate this value is. 

I have the First Ascent Aero 5.5 and am very happy with it but need a mat with a bit more insulation. It ticks the boxes from a weight, height and packed size perspective but just want to be sure it is warm enough for the berg.

Weight (Kg): 0.465
Designed For Camping, Hiking
Dimensions: 180 X 50 X 3.2cm
R-Rating: 3
Packed Size: 16 X 12cm
