John H.wrote a review of Big Agnes Two Track Sleeping Pad - Mummy on March 18, 2016
Familiarity: I've put it through the wringer
Not the lightest but quite durable and reliable. I fold it in such a way that I use it as pad for my back in my pack. From Mt Shasta to Mt Rainier, it has never let me down. One poor fellow on Rainier had punctured his ultra light sleep pad and did not sleep well. Everyone was jealous when I told them I got a comfy 4 hours sleep before summit run.
"Sleep well tonight, tomorrow could be rough!"
