"I have the red -25 20"x72"x2".
I have used this pad in Tongue river cayon Wy of March with 12" to 15" of snow at 15 F degrees. Not once did i get cold through the pad. I use this pad year round. It's light, warm, and comfortable.
The only draw back is if you have a slik sleeping bag and if you are on a down hill slope of any kind you find your self and sleeping bag scrunched up at the bottom of your tent. Other then that I recommend this Pad to anyone."
