User Review: Big Agnes Insulated Air Core
Price Paid: $55
Nothing really wrong with the pad I just would choose differently in the future, especially if camping in really cold weather.
I bought the mummy shaped pad and it is about half the width of my sleeping bag, so sliding off and always being half on-half off is inevitable. Also despite the insulation the pad does not insulate very well. I went camping in Canada this past March and was up the entire first night shivering (Despite having a -15 bag). I could literally feel myself losing heat from the ground up. My friend, with a much lighter sleeping bag but using a foam pad, was much warmer.
It does compress pretty tiny though, about the size of a Nalgene.
