I bought it at the advice of another member last fall, but did not try it out until the last few weeks sleeping on it in my friends spare room. I have decided again like all air pads I have tried I do not like it. I used three different models of the Thermarest with no luck either. I have gone back to using my 37 year old Ensolite pad.

I bought the Air Core pad for about $79. I am asking $50 Obo. Its the 40" length size. Its Red on top and grey on the bottom.

This is what Big Agnes says about it:

The lightweight and compact Big Agnes Air Core sleeping pad helps ensure you enjoy a comfortable night's sleep on summertime backpacking trips.

• 3.25 in. thick pad is waterproof and lightweight, and packs down to the size of a Nalgene water bottle
• I-Beam construction eliminates welded seams to reduce cold spots and ensure quick inflation and deflation
• Nylon on the top and bottom stands up to regular use in the outdoors
• R-Value of 1; comfort range to 35°F
• The Big Agnes Air Core sleeping pad includes a stuff sack and repair kit
