R-value 7.5. That number is the whole argument — this is a genuine four-season double that resists heat loss into frozen ground instead of wicking it out of you all night.
Three inches of high-rebound foam, a 3D sidewall that keeps the edges from collapsing when you sleep near them, and a built-in pump with dual valves so you're not hunting for separate gear at altitude in the dark. PVC-free waterproof fabric throughout.
