I'm looking for recommendations on an ultralight sleeping pad. I'm trying to go as light as possible but also be somewhat comfortable. I'm just curious as to what people have had good luck with. I'm currently using a Big Agnes mummy, non-self inflating pad that weighs around 16 ounces. I like it, but would like to go with something lighter. For some reason, as I get older, all the stuff that I'm carrying on my back seems to be getting heavier. So, what is everybody else using that they would recommend?
