Why do these cost more than a similar chair that includes its own padding??? Even so I paid the extra so that I can save the weight and room in my pack. I already carry a thermarest for sleeping - putting it to double duty in a chair with a back is simply brilliant! Works great, does what it should, and weighs practically nothing. What's not to love?
